Game crashes when enemies enter dongeon, also in multiplayer

I cant complete the tutorial, it freezes when the enemies come into the dungeon. I also don't get very far in the heart of gold expansion, and multiplayer also freezes on me. I've tried not using usb headphones, and tried lowering the visual display in settings.

I am using windows 10, 64 bit, I have 8 gb of ram.

my processor is an AMD A4-6300 APU with Radeon HD

and my graphics are 3.70 GHz

thank you,
