I Downloaded MOHAA Demo both MP and SP and both start up with a Gray Screen! and it freezes. Ive looked back at past posts and have seen stuff like reinstall Direct X and OpenGL how do I reinstall them.... and I saw one that renames a file and couldnt figure that one out either.. Is there other people with this problem.. I have a Nividia(Dell) Graphics card and got my comp a month ago so it's a new card.. anyways thanks in advance..
I really wanna try out this game!!
Maverick!
