Yeah I see, maybe something kept going into the game install and kept the renders. Usually the best course of action when doing a fresh install is deleting (or keeping them somewhere for safe keeping) both the old install and the game appdata folder, and then yes install the game. Because if you do it backwards and run the game and then delete the saves/persistent something can go into the game and put those renders unlocked forever and ever, it really depends on how it is coded I guess hehehe.
