dkienle said: I can open a "New" QDF file but my old QDF file fails. I have attempted validate and repair operations which finds no errors and opening backup files without success. This started after the last update between 10/23 and 11/6.
have you tried restarting your computer after this happens? You may additionally try uninstalling the Quicken software using the steps listed in this Support Article, then deleting Quicken from the Program Files (x86) folder. You may then reinstall the software after following those steps using the steps listed here.
I look forward to hearing about how these steps work for you.
