Have you encountered issues?

I am got the extra year of updates and kept my QuickBooks Desktop and my Windows 10.

Now I am at end of year and suddenly my Bank of America transactions will not import, and I am stuck. I have tried everything QuickBooks and Bank of America have thrown at me. Over ten hours worth of research and attempted fixes. Bank of America says it is Quickbooks' fault. The only thing that would make sense would be that I am on Windows 10.
