SLK isn't very well documented, and an error code like this isn't a great help. Remember it has no offical support from M$. As this is an extension of sharepoint you should be looking at the error logs.
I'd start off by looking at the windows event log (at the host server) for more details that it has some pretty helpful information there. Open up Event Viewer and look through the Application Logs for any SharePoint related events, that might help you figure out what is happening.
