Ok, so I tried the skidrow release which should be the retail release and it still crashes... but ironcly the Promo version of the trainer that is used to test to see if the full trainer is compatible with your copy, works perfectly fine.. no crash at all...
So something within the full version of the trainer is at fault.
the promo doesn't rely on code injection like most of the other options do. therefore likely something is blocking the trainer from injecting code into the game space.
just as pwizard said.
please notice that if there was a huge problem there would be multiple posts of this not working. something on your computer is 'protecting' you from malicious software whether it is your Antivirus, anti malware, your firewall, etc.
The only other problem is that you have the wrong version of the game.
best,
