I have been having this issue downloading from CitiBusiness Credit Cards into Quicken 2006 for Mac (using direct connect). Many calls to Citi have resulted in repeated assurances that it will be fixed in 48 hours.
However, I think that I have discovered some magic on the Intuit site that fixes things
in my Quicken software itself. Evidently, there are some certificates that need updating inside hte Quicken bundle.
Here is the link to the
Quicken Answer ID 7368The solution is sort of bizarre, and the directions are sort of broken.
You basically download a DMG archive (the link is at the end of the page above), but the downloaded file is not named what the page indicates. However, if you double-click the file (which is just named "Quicken") it mounts a volume with the "Quicken Certificate Updater.app".
Then,
instead of double-clicking this app, you find your copy of Quicken and drag it onto the app.
You need to authenticate as admin user (for some reason), but after Quicken is updated you can launch it and you should be able to download transactions.
At least, it worked for me for downloading from CitiBusiness Credit cards.
