In the last 10 days i haven't received any new task from any of my projects.
I haven't changed anything in my setup and I've automatic connection on every project but 3.

Any suggestion?

Thanks

This are the last lines of the Event Log

In the last month i've received just a bunch of wu. In the last 2 weeks i have received only a climate prediction wu that will take >400 hours to complete and nothing else.
Is it normal?

How large is your cache ("connect to every projects about every X days" setting) set to? The client shouldn't download more work than it can complete in that time, though if your client has never successfully completed a CPDN unit, it may be overly "cautious" in its estimate for completion.

It seems there was a problem in the options. I've clicked "Clear" to restore web based settings and now it's downloading some wu.

Thanks
