Server Status 'Offline'

[Stephen]

I'm new to running Tor as a server. I've recently set up a Tor relay node on Win XP using release 0.1.2.10-rc which I've configured using Vidalia. My node is acknowledged in the list of servers and for a few hours it was advertised as being online but now my server status is advertised as 'offline' even though I continue to run Tor & I am online. Any explanation/advice would be appreciated.

Regards,

Stephen
