Kevin, I don't know if Bruce has given you these instructions but try them if you don't think they are too complicated, or perhaps you have a friend who can try it for you. It's all predicated on the idea that you're using Windows, not Apple. I don't know how to do it with Apple.
Thsi may not work but it also might work so it's worth a try (Laura, if you see this in the next week or so you or perhaps your son can try it as well).
What you're attempting to do is to "flush" your DNS cache (DNS = Domain Name Servers). It means you will be flushing out old information from a cache stored on your computer. YOU WILL NOT BE LOSING ANY IMPORTANT INFORMATION and it could get rid of the erroneous information stored in your browser(s) cache(s)
To begin, click the start button at the bottom left of the computer. I think you know what that is.

.
When you click it, at the bottom of the long tab is a space that says "search programs and files" at the end of the space is a magnifying glass

In that space type cmd (it doesn't matter if it's upper or lower case). This is telling the computer to give you a command prompt. A box will open

You will see that at the top of the box it says
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\Kevin> (or whomever you have listed as the user/owner of the computer)
At the end of the line that says
C:\Users\Kevin>
Press the space bar once (you should see a flashing cursor and you will see it move one space) then type ipconfig/flushdns (exactly as you see it here) then press Enter or Return or whatever that key is called on your keyboard
C:\Users\Kevin> ipconfig/flushdns
After you press Enter/Return/Etc. you should get a message that says
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.
C:\Users\Kevin>
As I said, this may not solve the problem but it's helped me in the past when I need to clear out some information from the DNS server/cache. After you complete this I would suggest re-booting the computer to get a clean start. If you're uncomfortable doing this I understand but it's simpler than it looks and sounds.
Good luck and I hope to see you here not on your phone!
