Steinberg Licensing killed Groove Agent 3

I’ve been using GA3 since 2008, lately under Bridger. It’s a core part of my writing toolkit. I upgraded to Steinberg Licencing and it wiped my ability to use this, even though I still have the original DVD install (which I used) I’m guessing it’s not “currently supported” The nightmare continues. Can I have my old licences back? Is there any way to go back from Steinberg Licensing? I can’t load songs with GA3 . . .
