My discovery on my end is that I think it does not like any backup files for the company....why now...who knows.  I restored a client of another employee and I did not have that client anywhere on my computer...backup folders or anything.  I had no problem opening it or anything but she can't access it on her computer.  So when I tried to restore one of my clients from a backup from another employee's computer, I got the same pop up message you did which I had been getting a lot.  So I went in the drive folder C:Easy\W and just decided to test and delete all the backup folders that were in there plus delete the client from my company list.  I also made sure any files associated with that client's id that had a current date in C:Easy\W were deleted.  I then tried to restore from thumb drive again for the client and went in to open it and it opened right up.  

However, for some reason(and I might have deleted a file I shouldn't have), the payroll journal shows the payroll and deductions fine but it is not showing at all on the earnings report.  So not a total victory.
