Now with the new update i get memory crashes....mono.dll related
Will need a bit more info other than just mono.dll related, use event viewer for the faulting module or post the debug log, better yet post all you can.
Otherwise try starting from scratch
Delete trainer and all files in
C:\Users\USERNAMEHERE\AppData\Local\Temp
C:\Users\USERNAMEHERE\Cheathappens\Work
C:\Users\USERNAMEHERE\AppData\Roaming\Cheat Happens\0x90
Reboot PC to clear excess memory, get a fresh copy of latest trainer and
make sure trainer in is folder excluded from virus scans. Empty quarantine folder if needed.
C:\Users\USERNAMEHERE\Cheathappens
may need to be added to exclusions as well. Run trainer as admin and try again.
