Can’t rename/delete a job in SQL Management Studio 2005 Standard

I am having trouble deleting a backup in the SQL Server Agent, under jobs.

Here is the error message:
“Attempt to retrieve data for object failed for Server ‘NoobSrv1’ (Microsoft.SQLserver.smo”
“The job ‘[noobackup]’ does not exist on the server. (Microsoft.SQLserver.smo)”

Any help would be great!
