I recently downloaded the demo version of Unreal Tournament 2004 for my OS 10.3.9, and when I looked at the file, it's extension was in the dmg format, but with a .bz2 at the end (it looks like: filename.dmg.bz2). How would you open such a file? My computer won't automatically open it because there is no program associated with such an extension. Your help is appreciated. Thanks in advance.
