After updating to the latest version of Quicken (R55.15) about a week ago, every time I one step update, my Discover Card fails with CC-502.
If I immediately hit "Try Again", it updates just fine.
Financial Institution: Discover Card Method: Express Web Connect. (I'm hesitant to change that as I also have Discover Bank and it took a while for them both to update together right.)
Any suggestions? Am I the only one?
