Napoleonic wars keeps crashing

Hi guys I've just bought this game few days ago and tried to play it today. Everyting was fine, but only for few minutes till I tried to fire a musket. It crashed.  I opened the game again and it keeps crashing and crashing while firing a musket. Not always but its like 30% chance to crash on shoot. Any solution to that?

Sorry for my english

Have you tried lowering te particle settings at the options?
