OMG what a fucking hassle.......
I reinstalled CoH..... it did not fix the problem.
While scrolling through my folders, I found the issue. The 'grasunpacker' module file was on my D: drive, but
not inside the 'Mygames' folder.
I can only assume that world builder was seeing this module first, created a folder for it, but then did not recognize the game file?
?? That would explain why it created a new folder every time you tried to start world builder.
Anyway, I did not need to reinstall, I just needed to delete that module file.
Thanks for your help anyway Leo. Try the clown porn, you may like it.
