I can't import from serato after updating to 1.77.0. I get an error saying to "Please quit SERATO first!". Serato isn't even open. I wouldn't be upset about it if I could just download and install an older, working version, but for some reason none of the previous versions are available for download.

For a subscription service I expect to be able to rollback to previous versions especially for scenarios like this. Please consider making this change to your operations going forward.
