Resolved Completely new to this...

Im trying to download and use a GTA V file from the site, I can get the files onto my usb, but whenever I try to load them in the game it says the file is damaged. Does anyone have any insight on how I can fix this issue?

 

did you replace the ID's on the save you downloaded with your own ID's from one of your saves? once you done that you need to rehash/resign the save then transfer to usb.
