Purchased DLC is marked unpurchased in store
I have been chatting with support for almost 3 hours now and had multiple people basically call me a liar and tell me that what has happened is impossible.
I originally purchased all of the story DLCs, including the Overlord and Arrival DLCs, from BioWare years ago. Just recently I went to reinstall ME2 and when I reinstalled the game Origin let me install everything but Arrival. Chat support fixed that in about 10 minutes without any issues and it was great. Well, now that I am ready to play the game, every time I open it it says that Overlord can't be authorised and to sign into the Cerberus network.
I went back into Origin it shows that I need to purchase the DLC. The page on the BioWare website doesn't show it either.
None of the chat support people will answer how I was able to download the DLC if I didn't purchase it, they can only see that it's not on my account, and will not help me.
Chat support directed me here.
