FM Pro 11 no longer running backups
In July I started the update process to FMP 12. Upon learning that the files would no longer be compatible with earlier versions (FMP 8, 10, etc.) I reverted our system back to FMP 11 (currently undecided how we'll move forward with the update). Ever since, the system has not been running back ups at regular intervals, or at all for that matter. How do I fix this and/or set it up again for FMP 11.
Thanks in advance!
