After reading your concern, I have a couple of suggestions. It sounds like a browser configuration error. I am assuming you are using Internet Explorer. If so please follow these steps:
- Click on the Tools and then scroll down to and click on Internet Options
- If you are using IE7, scroll down to Browsing History and click on Delete.
- Delete all of your Temporary Internet Files and Cookies
- Click on the Security Tab and then reset all zones to default level.
- Click on the Advanced Tab and then Reset and the bottom of the Window to restore all settings to default.
The next suggestion that I would recommend is to download a backup browser such as Firefox or Opera. I personally use Firefox and have actually made it my default internet browser. Here is a link for the free download. http://www.mozilla.com/en-US/firefox/
Mozilla offers a free plug-in which will will allow Firefox to open a website using Internet Explorer for the specific sites that will only work with IE. I recommend picking this up as well. Here is the link for this add-on.https://addons.mozilla.org/en-US/firefox/addon/1419
If neither of these suggestions correct your connectivity issue. The next thing that you should do is revert your computer settings back to an earlier date using the system restore command.
- Open up your Start menu and click on All Programs.
- Click on the Accessories Folder.
- Click on the System Tools folder.
- Open up System Restore.
- Make sure that the button "Restore my computer to an earlier time" is selected
- Click the "Next" button
- Click on a previous date, one that you know all settings of your browser were functioning properly.
- Click "Next" and follow the prompts.
This should fix your problem.
