Common Internet Service Provider (ISP) connection problems
In order to access your account via the Internet, you'll first need to log on to your Internet service provider (ISP).
Sometimes you may find it difficult to establish an ISP connection. Among the reasons for this:
  • Your ISP's server(s) are down.
  • Your ISP is already handling a large amount of traffic, and is unable to take your call/connection at the moment.
  • Your system's modem settings are incorrect, or some part of your communications software is incorrectly configured.
What You Can Do

If your ISP is busy, you might want to try waiting a bit and see if you can connect later. However, if there's a problem with your ISP or if you're having software, configuration, or hardware problems you might need to contact your ISP directly and talk to their technical support team.
Understand Browser caching problems
Web browsers have the ability to "cache" pages. This process involves storing copies of pages you visit on the Web so that you can access them more readily.
How do I understand caching problems?

Browsers will store pages in two ways: in memory (for at least as long as you have your browser open), and then on your hard drive. Your browser's settings enable you to control how much memory and hard drive space are used for this purpose.
The advantage to caching is that it can be quicker for your system to retrieve a page from its own memory than from the Web. The disadvantage is that when you view a cached page, you might not be seeing the most recent page, but something older.
For example, let's say you've made some changes to your account online, and then logged off your account. The next day, you log on, and don't see the changes- rather, you see the old page held in your browser's cache without the changes. To bring up the most recent version of a page, press and hold CTRL while you click Refresh in your browser's tool bar.
Fix a Browser caching problem
There are two ways to remedy browser caching problems.
How do I fix a caching problem?

You can:

  • Clear your memory and/or disk cache. Your Web browser's help function should have a description of this process.
  • Force your browser to reload a new page from the Internet. You can do this by holding down the CTRL key while clicking Reload or Refresh on your browser's tool bar. This ensures that what you're viewing online is the most recent and up-to-date information.
Clearing Computer Cache to Improve Browser Performance
Your browser will cache (or save) Web pages that you access frequently. This decreases download time because your system does not have to reload a page each time you access it. However, it can be a drawback because: (1) Your computer is accessing the saved version on your computer rather than an updated Web version; and (2) The cache can get full quickly. You should clear the cache regularly to increase browser performance:
Internet Explorer 5+

  • From the Menu bar, choose Tools Internet Options.
  • In the Temporary Internet Files section, click the Delete Files button. Click OK.
  • Click OK.
Internet Explorer 4+

  • From the Menu bar, choose View Internet Options.
  • In the Temporary Internet Files section, click the Delete Files button. Click OK.
  • Click OK.
Netscape Navigator 4+

  • From the Menu bar, choose Edit Preferences.
  • In the Categories column, click Advanced (the +) and click Cache.
  • Click the Clear Memory Cache button, click OK.
  • Click the Clear Disk Cache button. Click OK.
  • Click OK.
AOL Browsers:

The AOL browser is, by default, Internet Explorer.
Browser Errors
If you try to access parts of the HBNGroup.org site that require a 128-bit encrypted browser, you will get an error message. If you wish to proceed to that part of the site, you will need to install a 128-bit encrypted browser. If you need to upgrade to a 128-bit browser, go to Downloading and Installing in this Help section.
The 128-bit encryption error messages are as follows:

"Netscape and this server cannot communicate securely because they have no common algorithm(s)."
Internet Explorer:

You will get two messages. The first message will display even if you have a 128-bit encrypted browser: "You are about to view pages over a secure connection. Any information you exchange with this site cannot be viewed by anyone else on the Web." Click OK. If you then get the following message, it means you probably don't have a 128-bit encrypted browser: "The page cannot be displayed. The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings."
AOL Browsers:

The AOL browser is, by default, Internet Explorer.
