I have an old Passpoint Plus 2.10 application that runs on Windows XP. For the past couple of months a problem has been occurring. I can assign a card certain access and enable the card for use. It will work as expected. Then at some point, sometimes within 24 hours, the card does not permit access.

2/6/2013 7:42:33 AM ACCESS DENIED Access Point 2 Unknown Card REASON: Card Unknown.

This randomly happens to cards old and new.

The only event I noticed overnight was CARD EXP COUNTS BACK UP by System. I don't know what that mean or if it is related to the root cause of my problem.
