Hi, My one PC is not picking up any work. when I do a manual update the messages I get are as follows:

7/4/2008 09:07:43|World Community Grid|Sending scheduler request: To fetch work.  Requesting 43200 seconds of work, reporting 0 completed tasks

My other PC is still crunching away, so doesn't request anything when I refresh, so I'm not sure if this is PC dependant, account dependant, or if it's general.

I've tried the following:
1.) Rebooted
2.) Detach & reattach
3.) reset all preferences to default.
4.) checked my results from that PC, and other than 2 pending validation, they are valid, so it's not that.

Anyone got any ideas? [Or is there something generic here?]

Regards,
Peter Bellis
