"3ds max" 2010 file opened in "3ds max design" 2010 instantly crashes

howdy

i have worked with several different files, on different computers at home using 32-bit on one machine and 64-bit 3ds max on another, and when a 3ds max file is opened on pc’s running 3ds max design (at two completely different offices) the file instantly crashes.

the only work around i have is to merge the file into a new black one or, worst case, flatten the file first before merging.

does anyone else have this trouble?
