I downloaded the level 127 mod while at level 50. When I go to level 51 the game stops and goes back to the desktop. please help

I don't use the level mod but . . . usually if a mod doesn't work it is installed incorrectly or is broken by a new patch. Don't know if others are having problems with the mod and the GOG version but someone will post here if they have info.
Look at this post for info on installing correctly . . .=)
Edit: Replace the sierra folder name with GOG.

Sorry Kezardin, we must have been posting at the same time . . . =)
