If you haven't rebooted Windows since you installed the latest software update, please do so now and then try Quicken again.
Still not working?
Let's try some "Troubleshooting 101" to ensure the Quicken software is installed and updated properly and that your data file is in good working order. Please perform all the steps in this document:Troubleshooting 101 - Fixing Software Installation and Data File Problems
If that doesn't help solve the problem, I'd say it's time to call Quicken Support on the phone and request help. Let them do a screen share session with you to review the situation on your computer, to determine the nature of the problem and to figure out how to fix it.
