Yes, I experienced something very similar.  I had a hard drive that crashed and had to be replaced.  I run QB Enterprise (Desktop).  I called the Help Desk for assistance in reinstalling.  I was told my backup files were corrupt.  I was over a barrel and paid the $1231.99.  I had been told it would take a maximum of 24 hours to repair the files.  I called after 24 hours, no files.  The gentleman on the other end (Indian), "Brian Wilson"  (I had assumed the name given was for the ease of American customers), got cross as if I wasn't supposed to have called back.

I stopped payment at the back.  Ouch!
