Wonder if anyone else has/had this problem. Whenever I try to decompile the Allied model with Cannonfodder's MDLDecompiler, it crashes right before it can give me the actual files. Can't seem to figure it out and really wanted to work on some British models.

Its been doing it for ages. One of the Source updates broke it and since Cannonfodder left the scene it's not been fixed. There was a version by a guy called Erik that works a bit better but it still doesnt decompile everything.
