@FoxtrotDelta I have done that twice now, and all it does is do a big download, eats up my data, I have a limited data cable ISP, but it doesn't seem to fix the problem, by the way I have the non steam version, I doubt that makes much difference though. One thing I forgot to mention as far OpenIV goes, when I open I run the ASI manager to defaults to ASI loader not intstalled and OpenIV.ASI disabled, and if I don't install both, the game will crash with the corrupt game message, is that normal? I just found a thread on here that seems similar to my problem unfortunately the thread died, https://forums.gta5-mods.com/topic/459/corrupt-game-data-when-disabling-asi-manager-and-asi-loader "I have to delete the files and then run a verify on my files, which usually results in about a 2GB download. I can't work out what gets corrupted or why." Kind of what happens when I do the verify, I can' afford the bandwidth if it's not going to fix the problem it's just a waste.
