Backup stopped working

It worked initially, but I didn’t want to use the default setting of a daily backup.   When I changed the frequency, it simply stopped working.  There aren’t any error messages. I’m using the free version of the program 

Hi, what settings did you change, can you please make a screenshot of your backup settings from Tools > Settings > General > Backup? What version of eM Client are you currently using on your computer, can you please check for the exact version number in Help > About?

You should also be able to schedule the automatic backup task in Windows Task Scheduler.

Thank you,
