Having the same problem as others - trainer version is 1.4.5427.111, game version is the Origin 1.4.5427.111 version. All current DLC is installed, and both trainer and game running as admin. No joy ...
Could something in the DLC be fouling things up somewhere?
Tried running as admin (N7 Collectors Retail Disk) out of the origin games/me3/etc folder with no success for my issue - may be a DLC weapon issue i'm not sure, but unlimited ammo and no reload don't seem to function at all, any ideas?
before i posted this i tried with one of the stock snipers, still no success
edit: I think the problem is the origin/ME3/texmod ballsaround workaround, shields and health work but ammo doesn't, probably something to do with that
