Steam Games FarCry3 and Victor Vran use to work now getting hard PC crash

Was using wemod to play both these games with no issues. However about
a week ago when I try to play either games with wemod my computer gets
a hard crash before the game starts. I cannot use ctrl alt del to get out of it.
Only thing that works is a computer reset. This happens every time. Was
wondering if anyone else experiencing this kind of fault?

Update - when I tried to install the latest update it failed. I followed
the instruction on how to uninstall wemod and downloaded the
latest version (after turning off my virus detection program). After
installation and turning virus program back on all is good. Farcry3
and Victor Vran no longer crash my computer.
