Hey try this....See if it works for you.

Game Crashes at Splash Screen......................

If you are having the Warrock.exe crash at the splash screen (Tank) then try the following.

Move the Warrock folder to the root of your C: drive

Example: C:Warrock

We have found a bug that is caused if the game is installed to a folder that has a name longer then 30+ characters. The same goes if you have installed the game into to a subfolder and that the total character length of the folder and sub folder exceeds 30 characters.
