QB Issue Resolution:

You cannot run that program on W10; it was not even compliant with W7.

Further, your data now is 9 year behind current. You are putting it at risk that is will not even update to the current program. Or, it might need interim jumps. Intuit only supports program for 3 year life cycle.

Only QB 2015 and 2016 are supported on W10.

Pro still is very affordable and 2016 is under $200. Time to upgrade. You will be amazed at the new functions and tools, such as sending transactions as email from the program.
