Hello @Flying.Fijian
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues downloading your DC accounts. I'm wondering what exactly is causing the issue with you having the error on all your DC accounts. One thing we can attempt here that's been used in prior posts is to close the program then reopen it. Once you've done that try downloading again and seeing if you're able to get your accounts working again.
Let us know how it goes once you're able to try these steps. From there we'll better understand our next options.
Thanks,
Quicken Francisco
