Gratuitous Tank Battles Crash

Greetings. After switching to a new, more powerful laptop, I have found that my GTB is unplayable. Upon starting the game, attempted through both Steam and through the actual .exe file, I end up with the following notice:

Failed to initialize 3D engine:.\srs\Game.cpp 356.

I’ve had no luck finding the solution on Google nor on the steam forums, and have already attempted the fix through deleting the GTB folder in /documents/my games, or through playing with the prefs.cfg file to force it into windowed mode.

My laptop has Windows 7 64b and the game worked previously on my Vista 32b. Any assistance would be greatly appreciated.
