Hello, i can see my project in the list projects but in the task there is nothing so i can't begin the project.
I have syncronized my project with BAM! and the website.
Where is the problem?

27.05.2016 00:27:23 | GPUGRID | No tasks sent
Why?
27.05.2016 00:27:59 | GPUGRID | Requesting new tasks for CPU
27.05.2016 00:28:00 | GPUGRID | Scheduler request completed: got 0 new tasks
Is the project 'done' ???

Check the server status page at the project, it will tell you how many tasks are available.

Well, it's called GPUGrid for a good reason - there are mostly only tasks for GPUs, graphic cards - and your host is requesting for CPU work.
There can be different reasons for your host request:
1. Too much GPU tasks already at the run
2. Settings on the project are wrong
I guess it's the latter and you have to look after it.
GPUGrid has rarely CPU work these days.

Okay then i choose another project...
Which settings can be changed and where? Did you mean on the programm or here on the website?

Ohh why has GPUGrid so rarely tasks, i want to help.

As said, I meant the settings on the project. Go to GPUGrid and check in your account for the "GPUGrid settings" and look, if the options "use CPU" and "use NVidia GPU" are activated.
Of course you don't have to that it if you don't want to crunch with your graphic card - that depends on the performance of it anyway, there are (very) long tasks available right now. But without a graphic card below a NVidia GTX 560 you won't have much fun probably.
