Diablo Hack Data File (FIX)

This is a very simple issue to fix and I've noticed it being asked around on alot of forums so I figured I would post the fix.

Just be very careful and make sure you follow exactly or the registry could become corrupt. When you get into regedit, under HKEY_CLASSES_ROOTS, go to the .dat and on the right side you should (Default) you are going to want to modify the data entry back to just DatFile. It may be listed as D2Diablo.DatFile or D2Trainer.DatFile etc. you just need to make it DatFile and everything will be normal.
