Hi everybody i'm a new enthusiastic user of the BOINC network and i'm currently in 2 projects:
Aqua@home and Primegrid.

I'm continously recieving the message on the title of the post :
"Message from server:Work not sent"
the message is marked red.

Now i'm sending you my message board to help you help me because i don't know if this is good or bad (i thought it was bad..)

Primegrid only has CPU applications. The work request is for work for the GPU, which Primegrid doesn't have work for.

Aqua says it doesn't have work for their GPU application at this time.

You'd better check their forums and server status pages to check on the availability of work for the GPU.
