Are you running any sort of firewall software, such as Zone Alarm, or do you have the Windows Firewall enabled? I doubt these would fully prevent you from connecting to battle.net, but it is possible.I've just installed TFT onto my new computer, but when I try to get onto battle.net it says something along the lines of "Cannot connect to Battle.net, You may be trying to access an invalid Battle.net server or if you have a modem you may need to manually connect to the internet first." I'm no technical whizz so I have no idea what the problem is. The internet is working fine outside of WC. Any ideas? Thanks in advance.
I tried accessing Battle.net on a windows account with administrator powers and it worked, and then I tried it again on the original account and it worked :S So I have no idea what the problem was. I never had a firewall turned on at the time of the problem though. Thanks for the advice anyway
