Did you try the suggestions in the
troubleshooting sticky for crashing when entering combat? (lowering graphics settings / texture quality, and for laptops with dual graphics, making sure the game was running on the discrete chip rather than integrated)
Can you start a multiplayer skirmish and play for longer, or in the Tutorial section from the main menu, enter the Training Grounds?
Please email supportdc@larian.com, with a description of the problem and the report.zip file generated by the
Dragon Commander support tool.
