Hello @NE_Girl Thanks for the update. I'm wondering here if we might be able to try fixing the issue you're having first by trying to import a QFX file so you're able to get some of your new transactions. From there we can work on getting your downloads back up and running.
To import a QFX you'll want to go to your banks website and find the area where you can export/download transactions. The article down below can go into more details about how to do so.

Once you've had a chance to do this let us know if your accounts are updated to the current date. The nicest thing about importing if we can choose the range we need to download so you shouldn't see any duplicates. let us know how it goes!Thanks,Quicken Francisco
