Redeem Code not working

Hi, I couldn’t get BL3 to launch today after 19 hours of played time. When I went to reinstall and redeem my code it says the “Code in not in Active Status”. I have my confirmation email from last month and proof of purchase, what happened that made my code invalid? I never got/asked for a refund and I played 5 days ago with zero problems.

some more info, i tried a complete Epic Launcher and BL3 re-install because I kept getting error status 88500005 and after submitting 3 tickets with no responses that seemed like a logical next step.
