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. Once you've done this try importing your QFX to the new file. Depending on the results we'll see what we can do next.
Thanks,Quicken Francisco
Quicken Anja said: Hello @Shaun,If your financial institution's reps give you pushback, what I can suggest is to call Quicken Support via phone and request to have one of our support agents make a conference call to your financial institution with you. Our support agent will be able to assist you in explaining to your financial institution why this error cannot be resolved on our end and that it will require an escalation ticket to be made on their end instead.Additionally, you can also ask Quicken Support to collect and review your log files to discover the internal error that your financial institution will need to escalate the issue or you can provide your financial institution with your log files as well.
