CAPI2 crypto errors in event log

The following errors have just appeared in my event log

Error 13/07/2010 11:04:56 p.m. CAPI2 11 Build Chain
Error 13/07/2010 11:04:56 p.m. CAPI2 41 Verify Revocation
Error 13/07/2010 11:05:00 p.m. CAPI2 82 Find Security Catalog for File
Error 13/07/2010 11:05:00 p.m. CAPI2 82 Find Security Catalog for File

Plus four more 82's...

Anyone know how to fix what looks to be some sort of certificate problem?

I and a few others are begining to get this problen the way to stop it is to go to services and disable windows media player network service. Seems that an update has screwed us.

Before making changes click on the serice and make sure it is not being used to support any other service.

for me and the others, correcting the certificate does not work.
