last i knew the halo trainer for 1.1 does not really work with "1.1" the reason is after 1.1 was released there was another mini update.
stupid bungie did not call ed it 1.12 or 1.1b but just left it alone.
soo you have to delete, rename, or move the TDATA folder for halo2 and run the trainers for 1.0
and i know this, i just put my controler down from testing them again
same for camra trainer
