I'd like to believe that, but since the 8.1 upgrade there are crashes all over the place for me. Also, the money cheat has stopped working (it flashes up as 999999 and then goes back to original amount - and if you are really lucky it goes to -999999 and ruins your game... AGH!).
I've had a lot of permissions problems after installing 8.1 so please don't tell me out of hand it cannot have "nothing to do with anything". In fact it is very likely to be a post installation problem I have to deal with myself(as will various other users). No need to get knickers in a twist.
as I stated previously, YOU DONT HAVE THE LATEST TRAINER.
please delete and redownload the trainer. If you are still getting the money problem, then your windows is giving you a cached version of the old trainer and not a new one (unlikely).
there was a hotfix that total war rome 2 crapvelopment team put out like 1 hour after we posted our original trainer. the new trainer works.
if you give the trainer admin priviledges, it should be able to access the game in all flavors of windows.
best,
Cal
