Well, I tried this on two different machines, Vista 64 and XP Pro-(yes it was downloaded via wireless on both machines separately)
I got the same error on the Vista box, but the XP gave me a slightly different one when I tried to force it -
After the "Couldn't connect on TCP" messege I got a (ACP_STATE_PID_ERROR) message - does that mean anything (other than I'm probably hosed?)
Thanks for your help btw - I'm still hopefull...
