I have the same problem today. I played for quite a while last night without any problem, but when I tried to connect to any poker sites this morning, my cable just wouldn't respond. I can also browse the web but just cannot connect to any poker sites. This is getting frustrating. Can anyone help me out please??
btw my computer runs window 2000 pro, I tried the advices above and it doesn't work.
Edit: Is it possible that my router blocked the connection? I am using linksys router and my other computer also cannot connect to any poker site.
