I don't know if this could be problem with size of disk. But I have free 184GB on D. And recently I had another disk put in my PC and thanks to that my D where I have Omsi is less full. But I don't think so, because another maps like Lemmental, Stadtr etc. don't have problem with this map translate.
Have you reinstalled the 4GB patch?
I use .bat which will always open 4GB patch and use it immediately
on omsi.exe and than open Omsi.exe ![]()
