re still getting a corruption message & you are using the 'mods' folder then it may be that edits have corrupted the entire 'common.rpf/update.rpf' (wherever you are installing it).
Dude! I'm a fucking dingus; LOL! I figured it out, then was still stuck, but got it!
So first things first, my initial mistake was trying to edit the common.rpf file within the root of the GTA V directory rather than via the mods method; (I didn't have a common.rpf in my mods directory, but I created it after that!)
Once the common.rpf file was copied into the mods folder, I made the change, but nothing was fixing it; so I opened up openIV, and I totally forgot that I had disabled the openiv ASI plugin; (Found in: Tools >> Asi Manager >> "OpenIV ASI")
Once I enabled that, I was able to boot up GTA V successfully, AND when I flew up to the ceiling, I didn't get those shit clouds!
Thanks so much for sticking with me while I got my act together! This has been great!
