Drakiar, I was also seeing a crash on loading screen issue, which I originally thought was the trainer too. Try updating your graphic card drivers. If you've got an nvidia card, update to the latest beta drivers from their website - that seems to have done the trick for me.

Thank you, i will try.
So Im confused... is it safe to use this in singleplayer while connected to battlenet to get achievements? I remember the ban wave with Wings of Liberty singleplayer. It seems some people in this thread are saying its safe, while some are saying only use it in offline mode?
Been using it in the single player campaign while still connected to bnet and so far no issues. Ofc can't know if they will go and ban us later, time will tell. But as long as you don't try to use it in multiplayer you should be fine.
