It should get a new one for you from the gwebcaches. Even then it might take a while to connect. If none of the hosts given to you from there work the first time, I believe gtkg waits a decent curtouesy period before asking again.

Also, you'll probably have to cycle all the way through your host cache before gtkg will resort to the gwebcaches, but I could be wrong about that.

Hope that helps,
