I've tried running as Admin and in XP compat. mode, but with no luck.
Edit: Updated to Update 4, using the newest Win8 compat. trainer, but the game seems to crash after a short period, after activating the trainer. Tried NO-DVD .exe to no avail.

Have you ran through the TTSG? Have you checked to see if your trainer matches the game version and will work with your OS?
