In https://microsoftmoneyoffline.wordpress.com/2010/10/06/cal-learners-review-fidelity-401k-citi-card-and-vanguard-account-info/ Ameridan posted the problem, and what appeared to be a solution. I tried that solution, and it worked once. Ken H had the same experience. The problem is an "Access Denied" message in the OFX file, and no transactions.
The situation is a little unclear at this point, but I thought I would post what I knew. I did some screen captures that could show the path throug the Citicard website.
As with Ameridan's observation, the Citicard site had been really reliable with PocketSense over a long period.
