Community ManagerI'm sorry you're still having troubles with this error, but thank you for the update!
At this point, I'd recommend reaching out to Steam support for a refund on the base game. Once the refund is processed, you can re-purchase it via Steam and register it to the correct EA account to clear these errors up.
Unfortunately steam is unable to issue a refund for me as I had already had gameplay of 21 hrs before I realized my store items were installed.
And live chat for EA doesn't seem to be available.
