@rulik99 My apologies, it just appeared that was the situation based on the wording. But since it is not the situation, just like ikt stated, use the mod folder that OpenIV can create for you to help keep your vanilla files untouched so you don't get banned. When you want to go online safely, the only thing you would need to do is rename the file named dinput8.dll (this file is the asi loader ikt mentions to disable) to something like 1dinput8.dll and the mods will not load nor be recognized by Rockstar. Rename it back to the original name to play SP with mods. I searched for a Lenny's Mod Loader on the site but could not find it, so recommend using OpenIV.
