I also used Keokri's suggestions; it worked fine for me. The secret is do the repair first, then do the 'file rename trick." The trainer now works just like it should, even the EZKills option; it looks like the root cause IS the files being moved. Good luck!
The trainers will not work due to Bioware sending out an update in 2011 after the last 1.02 Trainer was released in 2010. Until the trainers are updated, you will always get the "trainer cannot find game" message. The Trainers will work if you reload the game and do not update the game to v1.02 thru Bioware!
