Hi "No Expectations",
Well, the solution is alot more easier, than you could imagine.
First of all, please remove the current installation of VC:MP and then reinstall it, but this time
exactly to the same folder, where your GTA:VC is. Don't even create a new folder for it, just choose the main folder of VC.
After starting VC:MP, please locate the folder of VC and then everything should be fine. Thats all

.
Regards,
Greg
