I can't download tasks so my computer stands idle most of the time.

It started when I added Einstein@home to Boinc. Now I removed it and Seti@Home, reset all preferences to standard and then added Seti@Home to Boinc again.

But no new tasks are downloaded.

Edit: I'm sorry, I guess I was in the wrong forum when writing this.

There is nothing wrong with your settings. Two servers crashed on Oct 28, their replacements have been delivered this past Monday and they are being configured as we speak. Because they are swithcing a few roles of the existing servers, expect that it should be at least another two weeks before they're back up.
