Error in Subversion

I am getting the following error when trying to do an Update from
repository. I am using Eclipse.

Greg Holstein

Mason Companies, Inc.

And then I tried synchronizing and got this:

Problems reported while synchronizing SVNStatusSubscriber. 0 of 1
resources were synchronized.

  An error occurred synchronizing /masonweb: Error getting status for
