I just got a new PC running Windows 11 Pro. Installed quicken. When I open it a window pops up that I presume is for activating by using my Quicken ID. Unfortunately, that window is just a blank white window so I cannot activate quicken. I've spent the last two hours with Quicken tech support. They say something on the PC is blocking that activation window. Windows firewall is turned off. There is no AV installed. It's not a network or ISP problem as I have a laptop (windows 10) that runs quicken just fine on the same network and ISP. Suggestions anyone?
