Okay, so wasn't able to do anything to begin with as the "Play" button did literally nothing. I found the other thread here that said to download the DirectX files and I did that. Play button worked. But then - because there's always more - the game window did the whole "Not Responding" thing, which has never happened to me before on this PC.
I went to look for more info and the game window finally brought up server list, but it was blank. I have no servers to click on and there's no animation or anything in the window.
I've restarted my PC, checked drivers, and checked my firewall program. I've not unistalled the game and reinstalled, because that's a huge pain to deal with, but I'm about to attempt that. I just wanted to put this out here in the event it doesn't work and someone has some advice.
Thanks!
