I didn’t discover this one, so I’m just the messenger passing word on – KB 974571 (part of Patch Tuesday today – specifically related to Crypto-API/ASN1) will make OCS think it is an evaluation version that has expired. Uninstall KB 974571 and OCS works again. You will want to apply the KB once an updated patch, or an updated patch for OCS becomes available. I’ve verified this problem in my lab too.
