Pr0bleM

HI people! Since I re-installed ETS2MP I have a BIG problem. Its moar my PC than ETS2MP fault I think. And the problem is, my PC keeps saying that I doesnt have enough rigts for run the game or to access the ETS2 folder. I tried all, I have Admin rights, I looked at the properties of the ETS2 folder and its free for all users. Can someone please help me? I watched videos on YT, and there was a command to execute but it still without working. If someone could help me, would be apprecieted. I can speak Polish, German Spanish and English, so I accept answers in all those languages
