Don't use any of these characters: * ? < > | " : \ / (asterisk, question mark, left and right-angle bracket, pipe, straight quotation marks, colon, BACKSLASH, FORWARD SLASH). Also, don't add the .qdf extension; Quicken does that for you.
After adding accounts, see if you are experiencing the same problems in this test file.
Shannon M M said: Yes. As I mentioned, I had to perform this task just a few days ago when troubleshooting another problem with multiple bank account connections. So I’ve followed your instructions and the CapitalOne accounts were successfully added to the test file. But if I open my main file, the problem persists. Also, to save us some time, I also performed the Validate and Super Validate operations. Keep in mind that my main file was the newly created file I’d just copied a few days ago. Something keeps corrupting the account connections. It doesn’t make sense to keep creating copies and having to reconnect accounts until we know what is causing these corruptions.
Shannon M M said: Hi Jared, My active data file is located in the Quicken directory in Documents. Tried your signing back in suggestion and the program still freezes.
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.

Per the earlier discussion on this topic I tried completely uninstalling and reinstalling Quicken to no effect. This used to work, what changed?
Shannon M M said: When I try to reconnect my CapitalOne Quicksilver or SavorOne cards, Quicken freezes and goes grey. I then have to close the app with Task Manager. I have just recently had to toss a corrupted file and start reconnecting everything to a copy. Such a royal pain!
