Re: Bought DLC a long time ago. Do I need to buy it again? PC

@tdmorey You can try checking here: https://social.bioware.com/user_entitlements.php (just make sure you're using the same EA account). It should show you what DLC you own (for any Bioware game other than DAI) and allow you to download it (you will then need to install them, this method doesn't use Origin to install the DLC). Doesn't fix the issue of the Buy It Now buttons in Origin, but if you own the DLC, you can at least get it and use it this way. 🙂 

Also, if Origin previously showed you as owning the DLC, resetting or changing your computer shouldn't make any difference as long as you're using the same account. You could try uninstalling and reinstalling Origin, see if that fixes the issue, otherwise I'd suggest contacting EA, which you can do here.
