Right, turned my cable modem back on this afternoon, it was turned off from 23:56 last night to 12:37 today (for all you mathematicians out there that's roughly 12.5 hours

) but I still have the SAME IP ADDRESS!! So that's knackered me for starters! The lease expired at 12:34pm today and I acquired a new lease at 12:37pm, but the IP never changed.
It's in NTL's hands now! So I wouldn't bet on it getting fixed anytime soon :/
