I've recently upgraded to ZCM 11 SP2, and just before I did my update I started receiving a message that my System Update entitlement had expired so I couldn't receive updates. I thought that possibly updating the SP would fix the issue but it didn't. I did find a forum/TID that described how to find and reset the entitlement license, which I did, but I find that on a nearly daily basis (pretty much whenever I look at the setting) it shows as expired again, even though my licensing shows me valid to 2013.

Why does this keep happening? Thanks!
