If you're not getting F@H work units, try installing Rosetta@Home that's doing the same sort of thing: Join Rosetta@Home.
I have both clients running - when I have a F@H WU it takes the lion's share of the CPU and all the GPU, when I don't have a F@H WU Rosetta kicks in to do work.
Yeah, I've had to quit for a while, the client was interfering with the live streams even when idle and the risk of forgetting to disable it is too high, so until I figure out a way to shut it down and restart it automatically it'll have to wait
