A bit of a problem
 

Alright here is my problem, i updated SH5 to 1.2 installed the MMM mod and played it a few months, after i bought SH3, SH5 went to the background well after a few weeks i wanted to play SH5 again i started it up and noticed there was a new uplay screen i go to the game and press play and it says your game files are corrupt please reinstall SCR!@#W YOU. what is gone wrong and do i need to reinstall the game??

Thanks in advance

sounds like you may have got corrupted by some jerk screwing with it but dont fret, it might just be a pop up that means nothing and is just trying to scare you

run an adware cleaner to get rid of it but if its still there then with new things that just show up, usually going back to the last save fixes it so try that before you do anything else.

all they can really do is mess with your saved games if they do get into the system so its no big deal but making a new password would be prudent
