The regions exist for a reason. Im not sure what the reason is, but they do. And they hinder you. I'm not sure why so many people have mismatched Disc to DLC problems with skyrim. Its been a pretty consistant topic since i've been active on here again.
I HAVE THE SAME PROBLEM!!!! SOMEBODY FROM PSN PLEASE REPLY!
Why does someone official have to respond? Didn't you read my reply?
Unless your Disc and DLC are approved for the same region its not going to work. Also, I don't know that it can be refunded since there is nothing dysfunctional, you just bought the wrong one. I've never had this problem so try contacting support.
