Scott,
As you can imagine, if everybody had the problems you are having, it would be a big problem for us. I wish I could point to what it is that is causing your problem.

With all the possible browser hijacker programs (adware) and their multitude of behaviours, plus all the security programs (some just silently delete your cookies) and their behaviours, it can be very difficult to find out how these things happen.

Since you have multiple test computers, it seems like a connectivity issue. Please try it at work or a friend's house, just so you can see what "normal" service from us looks like. Maybe that would provide a clue?

I wish I could be of more help. I totally understand if you have to give up.

Jon
