I got the exact same issue!!
Tried to trash both the license file and the cache in the same folder, but no luck. Nomad Factory site tell me to re-authorize - and if on an already authorized machine, this should not take any more "seats" (I believe you can authorize 3 machines). But the Authorizer Tools...where is it? Not included in the Sonic Sweet installer unfortunately. And the one included in the ISP package is too old/not compatible with Catalina...
Please advice us how to reset the seats!

Just updated Sonic maximizer suite from 4.101 to 4.1. Now get error "failed to authorize. All seats are already in use."
Was working on this computer before. Please advise. Thanks.
