Deus Ex Alpha

okay so I have to use the fucking Gamespy internet explora now cuz my Internet explora and Firefox wont connect to any pages, wtf?

Please provide with more information.

What antiviruses and firewalls do you use?
Do you have Windows Firewall enabled?
Have you changed anything in the system since Firefox last worked?
Do IE and Firefox try to load a page, or they immediately show an error?
