Error cc-555 started showing up recently for me. In my case (Vista 64, Quicken 2009) the error is in the "One Step Update Summary" pop-up box. I click on the "Update Again" button in the lower right area of the pop-up and the transaction with Barclays goes through. An annoyance, a reflection of poor design and testing, but not a show stopper.

I fail to see any evidence of poor design and testing.
Financial institutions can "block" (and Barclays is blocking) Quicken from accessing their servers to download data. I don't know whether the block is for all One Step Updates, or just those between certain hours (both are possible).
There is more than one way Direct Connect can download. Typically users elect One Step Update, which aggregates a bunch of different user's OSU requests and sends them to the financial institution to retrieve transactions. This can create a heavy load for the fi's and they sometimes combat this by temporarily or permanently blocking such access.
Using Update Now (or, I suspect, Update Again), makes a one-to-one connection with your download request and your financial institution's server. This can succeed when a plain OSU will fail.
In any event, the problem in such situations, is with the financial institution.
You need to take the issue up with Barclays.
