corrupt game data
I think it was after i installed add on car.
MIne corrupted after I installed a Lykan Hypersport as a replacement. The file itself made the whole computer to crash and eventually the game as well. To anyone reading this, make sure you back up your files before adding a mod or add on, I learnt this the hard way. And please, don't add the Lykan or else your game will corrupt.
@SpeedBandit It's not the car. I also don't see how a car mod causes corrupt data, All three Lykans work fine. You probably installed it wrong.
Something in your mods folder is where it doesn't belong. The game sees that as corrupt data.
I had this same problem, both because files were in the wrong place or files were missing (like when I deleted a bunch of folders from cutspeds.rpf and ig_streamedpeds.rpf).
