Missing EV client 10.0.2 tab

Hi all,

we have upgraded our EV clients to version 10.0.2 and most of our Outlook 2010 users now don't see the EV tab -- even if the add-in is loaded (valkirye.dll) and the email messages have retained their grey vault icon in the readin pane.

We tried to uninstall (http://www.symantec.com/business/support/index?page=content&id=TECH53462) and reinstall the client, but it was no help. We also launched the ResetEvclient.exe application, no help.

Any suggestion? Thanks.
