The texture Pack for Battle OF Bulge has an error. Sometimes the system thereby comes to a hold. I think any textures there am incorrect. After a few seconds that stops coming to a hold again. But since that seems to 2 or 3 time in the play, it is disturbing. The first version of the Pack, without more installer, did not have this error. There one did not have to unpack however it gave problems, but those had I unfortunately no more on non removable disk: ( sorry for my bad english but i am german and i cant good write in english ;)
Shoot an email to Prowlinger, because Im not sure what the problem might be.
