When something changed
Ordinary reopening should restore the existing session or ask for the connected account. Recovery actions are for missing business data, a moved folder, a replaced computer or a verified backup restore.
Continue with the restored session or sign in with the account already connected to the business.
Use the application recovery screen to locate the existing business folder instead of creating a replacement business.
Install Fastbooks, sign in and restore a verified backup rather than creating a blank replacement business.
