Welcome to the forum!
Hopefully you'll get a response from tech support. If you do, please tell us what they say.
Are you able to use compatibility mode? (I think it came with one of the service packs for 2k?) If so, have you tried putting the .exe in compatibility mode before playing the game?
Also, did you install the version of Quicktime that came with the game? If not, you could try uninstalling the Quicktime you have and instead installing the version that came with the game.
