@Terraxxx365 Hi. You rarely need to reinstall your game. It's perfectly normal for Open IV to delete the line in dlclist.xml because it means the addon is not in the right folder. You shouldn't use the original folders. "When you hear hoofbeats, think of horses, not zebras"
Please send another picture, like the first one - i'm sure we can find the issue.
Also, please send a second picture that clearly shows where dlclist is, the one you are editing, not the original game one, in Open IV. Just to check the location, these things can get tricky but once they are setup everything will go smoothly hopefully.
P.S. If you are using the Steam version, do a verify integrity (not a reinstall). Sorry don't know the equivalent with the other version.

i will reinstall the game and see, i have it with the social club version
