Hi everyone, I really need your help. I can't use the internet on my computer because I can not open the internet explorer.I messed it up somehow.I have a compaq pesario.I've tried going to tools and following instructions,no luck.I have reset computer to previous time to see if that would bring it back, no luck.This has happened before.It usually happenes when I try to log on to a wireless network.This time it happened at my daughters house.I was trying to connect to her network and it asked me if I wanted to add to something or something like that, I said yes and then it happened.This has happened to me before and was told the IP address had changed.Also the subtext-something? I think it has the same problem now. Please Help, I'm lost without my computer!!! Thanks for your help.
