I have been using Quickbooks for over 30 years, but I am getting frustrated with simple tasks that seem to go crazy.  The latest is with Data Protect.  First, if I don't backup within 2 days, it drops me from the system and I have to "log off" and re-enroll in the data protect process before it will back up my files.  The second is that sometimes, even though I back up the files, the program or routine doesn't recognize the fact that the files were backed up.  Case today:  I backed up this morning.  I decided to backup again at 5:30 p.m.  When I started the backup process, the data protect screen showed the last backup as yesterday.  It was the same in the history.  But I know I backed it up this morning.  

What is going on?
