Forum:I don't know if I have Dark Arisen or not...

Can someone please help me out??

My mother bought me Dragon's Dogma right after the launch of Dark Arisen... But I wasn't aware Dark Arisen was being launched, so I only asked her to buy Dragon's Dogma. The cover of the game I have is exactly like the first Dragon's Dogma (not Dark Arisen). However, my Xbox 360 detects the game as if it were the Dark Arisen. Is my cover that is just the same but my game is the Dark Arisen, or is my Xbox messing things up and I don't really have the expansion, just the original game??
