Had some trouble with the trainer, and this fix worked for me. Thanks for posting this!
Good to hear ill add you to my list. So i can submit it when i get enough people. people that have this particular problem are hare to come by.
The fix i suggested. is really only for the people that have EVERY new trainer since then updated the Security Template a tear a go in march. i think it was march.
I would say for you Something is blocking the trainer. Even if your AV is off its still there. and can interferer with the trainer
