Modeler cannot load any BusinessProcess -- "link down"

My machine is shut down because of power down. When it restart, I found it cannot load any BusinessProcess from Modeler. (attached a picture)

I got error from serverName\e$\webM61\Servers\RepoV3\logs\repolog-20060705115238.log on “link down” issue.
