Welcome to the team!
What does it say in the "event log"?
I also just had a look on the project pages, and both projects are rather low on tasks to send out.
So you prolly just joined at the wrong time.
For gpu grid you might also check that you´re allowing the gpu to crunch. I might be wrong, but iirc its set to not allow the gpu by default. Sorry, I´m using a germany boinc manager, so can´t tell how its called in English, but if you´re in advanced view (or whatever its called), you can find it in the drop down menus there at the top
edit: going by ABs screeny above
you´ll find the event log under advanced,
and the setting for gpus under activity
