It appears that your system date was in 2009. That may have something to do with it...
Look at the list of actual assigned libraries or in the Explorer tab expand the libraries. You may have an issue with either SASUSER or SASHELP libraries.
Any time I see something like "used to work fine" then I look for what changed: Operating system or update, license, network or security settings if working with a server version, hotfix applied or whatever.
