Hi,
@Sneezy and @Owen., Thanks for your inputs. Replying to you after finding out the solution and playing ETS2 for an hour now. couldnt anxiously wait more. Though after a lot of digging found this article. I hope this helps anyone who might hv encountered the same prob. Cheers n happy trucking! (Turns out in regedit, 'Computer\HKEY_LOCAL_MACHINE\SOFTWARE\TruckersMP', the path is not the same as that of actual steam path from local files, this had happened as I had made a system clone backup for my windows and that had resetted the directory path)
