In theory, tomorrow's episode should be today's episode just postponed by 24 hours so the series link (which had set a recording for 9pm tonight before they postponed it) should have just moved to 9pm tomorrow. I haven't touched it, so I will see what happens later on this evening or tomorrow.
At this stage, it looks like they have cancelled the episode that was on the EPG rather than postponed it.
A series link won't kick in until the programme has been broadcasted therefore - it may not pick up the next episode at all, but I wouldn't expect it pick it up until the time that it was due to air has passed (my guess).
