Can't open garage band Error-1712

Hello

I can't open Garage Band (error -1712).

I believe it's because I had a drum software, on my Mac, BFD, that I got rid off since I last opened Garage Band.

Apparently Garage Band is looking for that ressource, but can't find it, so it won't open.

Can someone tell me how to go around that issue and open it anyway?

Thanks

Marc
