Have you had any problems with restoring the backup files from a 25.26 version to the 25.26 version (on a Win10 system)? As soon as I tried to restore, all payroll and AP is completely blank and when I try to run the utility system, is just freezes up and does not work. I am in the same boat and have already done the 

remove and replace with the 25 back to 24 version, but had to use the payroll run today for 26 and wish I had read your solution before I did that-HOURS if work trying to get this done and now finding out I will have to do it all over again!!

This is the worst software they have put out and I have been using this sine 1995-DOS version!!!!
