Amnesia and youtube

[Phorthios]

Hi there!
Earlier this week I saved a gameplay of myself playing amnesia (A custom history more concreatly) And I, in all my sillyness, activated the add program.
The point is, youtube said to me that i had to give them information wich prooves i can make videos of amnesia and earn money with them.
The question is ¿Can I? ¿Is it legal for me to do so? And if so ¿Is there any especification for it?
I'm looking forward for a reply. Thanks.
