My Site Organization Browser is Blank in 2010

This can happen especially if an underlying "User Profile" is edited or deleted.

The issue may present itself as an empty silverlight web part or if you clink "HTML View" of the organization you may receive an error "error processing this request".

To resolve:

1: Clear the end user browser cache

2: If Step 1 does not work Reset IIS on the SharePoint front end server.
