If I buy a digital good from someone on paypal, and they take it back, can...

...I get my money back? I bought some digital goods from someone for a video game, and I send them money via paypal. Now I am scared he might try and take the digital items back from me, if he does can I get my money back from paypal?

The item a gaming account, regardless of your opinion on this, I am wondering if paypal would give me my money back should he decide to report it stolen or something.
What proof would I need?
