New computer, Game frozen

Hi there, hopefully someone can help me out here. I recently built a new computer and I cant seem to get warmane BC server to run.
When I launch the game it freezes at the login screen, but the music is still playing and I can actually click buttons and type in my login info with the display being frozen. Im running an HD 5770 with an i5 2500k. As a side note, retail runs perfectly fine.

If anyone has the technical know how id appreciate some help.

thank you

I'm dumb, I thought I downloaded the new drivers last night but I was drunk and didn't actually do it...

I opened the game after installing drivers and rebooting, and it worked but when I exited and tried to open it again the same problem occurred. So its not a driver problem
