What does My Grid > My Projects say and did you make any changes at device profile level? Think not by the sounds of this, but if you connected the client before making your science project choices you will initially have received something out of the default "all projects" selection. After you've confirmed and completed the first tasks, you'll be getting HCMD2 jobs I'm sure, also because the system requirements are very low.

cheers, and do let us know if things work out.
