Warcraft III problem

[Raptorz]

Hey, I recently installed Warcraft III RoC and Warcraft III TFT and now when I try to go playing (when I open it) my screen just turns black, but my "Start-bar" (dunno the name in english) is showing. And only way to remove it is shut down the program from program manager... I have installed and uninstalled the game atleast 4 times now and cant get it working... If you want picture, I can take it for ya.

And btw, Warcraft III has worked for me before, so what is the problem now? (Was the very same computer before)

Thanks in advance and sorry for spelling mistakes.
