Originally this post was about how Pinnacle Station and BDTS would prompt with "Mass Effect not found". I worked around that by creating a fake "masseffectlauncher.exe" file in my Mass Effect directory and they installed.
Well, now when I launch Mass Effect, I'm prompted to re-enter my registration key. I DID successfully launch Mass Effect before installing the DLC, so I know that the DLC broke it.
The prompt was pre-populated with a code that it would not accept. I found the Pinnacle Station code from the EA Help article on the topic and tried that, but it wouldn't accept that either.
I don't have a registration code. I bought the game on Steam originally, and somehow it was transferred to Origin. It's been so long that I don't remember that process. I've played Mass Effect many, many times without this ever coming up.
