Well, so I have decided to buy UT3, and download RenX, I fully updated it to 0.555. But when I launch RenX I get the launcher, and it also has a Refresh server list button, which quickly turns to Refreshing. But it pretty much gets stuck on refreshing, and no server list appears, making RenX pretty much unplayable. What could possibly cause this problem?
I'm on Windows 7 x64, and internet with a cable...
EDIT: almost forgot, Steam UT3, attempted fixes are admin mode and XP SP2 compatibillity, to no avail, no recent changes.

please please please
