sounds like a cookie or domain problem.. is it happening on one PC? to all PC's? check your cookie domain.

Minto - are you running some sort of Norton Internet Security, or a Firewall of some sort?<br /><br />This is a common response to a cookie not being allowed to 'update' properly due to a firewall blocking its access.

Yeah, you either need to add your URL to your list of trusted sites, or turn off the Referer check in your config file.
