One of my client's files keeps getting the same error messages, pretty much daily.  Supposedly the software has "fixed the issue," but obvoiusly not.  It does not matter which machine I do a back up from, the client's desktop, my MS Surface or my office desktop.... same error.  Find it laughable that we cannot get a decent explaination about the error codes so we can fix the problem without QB Support having to dial into our computers - not happening on my machines.
