To report a crash I would need you to paste or link the HwRM.log and the .mdmp file (not the .dmp file), and the circumstances that it crashed, like during game loading, during the match, how deeper into the match (gametime if possible), which campaign was being used (HW1, HW2 or Raider's Retreat), which mission caused it, or any specific event if possible.

You can follow the example that will be posted in the MP crash thread.

The HW1 Campaign compatibility has been dropped temporarily.
