Thank you for taking the time to share the details of your experience and feedback with the Community, although I apologize that you have not yet received a response.
We'll need a bit more information to be able to assist.
Please take a moment to review the information available here and post back to let us know what version and release of Quicken you are using.
Do you use a VPN or have any 3rd party antivirus running?I would also check for a firewall or anything that could possibly be blocking a connection. At any point do you see a bug splat or crash report?
The more information you can provide regarding this issue will help the Community to better understand and assist.
When the validation completes, a data log will open in Notepad, please let us know if any errors or issues are found/repaired, and when ready close and re-open Quicken.
Please let us know what you find!
