I just had this problem earlier on a computer using Vista, but was able to fix it. For some reason, everything was moving slowly even at the logo (so I would hear the "projector turning on" sound, then 6 seconds later hear the Bit-Blot theme)
Problem was fixed by letting Windows Update pick my video drivers, restarting, and reinstalling. After all that I'm not exactly sure what did it, but the game is running fine for me now.
