game crash when using C&C: Generals: Zero Hour v1.02 +10 TRAINER

[Sams choice]

I have trouble with the original Generals crashing after I install Zero hour. I get a technical difficulties screen upon startup but just from the original, Zero Hour works fine but it seems to screw up Generals when I install the expansion. I wish I also had a solution. I'm not even using the trainer and have even tried it without a CDfix and a new set of original CD's.
