Fun AAR, Nozza. It's always nice to see more Dr Who goodness hereabouts! I hope you'll post about how your second outing goes - it would be interesting to see how things play out the next time.
As regards BTD, I'm guessing you're all based in England or Europe, so this may not be much help, but I've heard that the US branch of BTD is much, much more reliable than the UK bunch. Seems silly, but you might want to give them a try?
