Starcraft 2 trainer doesn't work

[iNvIcTUs oRCuS]

The Security Tools (avast!, spybot 2) are running in the background while the trainer is launched?
If so then its possible that one of these tools stop the trainer to work correctly.
Test it by this way...
Disconnect from the internet, exit all running security tools and then start the trainer. When it loads without any problems then its one of these tools...
