Yeah, I just found out the hard way that the infinite health and armor options are not working with the latest trainer from 2/11. The game must have updated when I wasn't looking, the exe file says version 126.96.36.19940. Oh well, these guys are the best at this stuff, so I'll just wait until an updated trainer.
Okay, I just tried re-downloading the latest trainer and then tested it. So far all the functions are working fine, I don't know what happened. If anyone is having issues just try re-downloading the trainer again, it worked for me.
