Hi All,
I am getting an error after I installed Livesite 2.2.1.
My TS version:

Windows 2003 ent edition sp1
Teamsite 6.5 SP2
Patch 65939
Livesite 2.2.1

While borwsing the directories under the workarea I get following popup error...

An error occurred executing command com.interwoven.ui.teamsite.filesys.GetDirectoryContentsCommand

The details button shows me this:
