Glad to hear that it worked out for you! I think that you have definitely earned a glass of wine or two tonight. For my part, I have also ran the Loughborough half mara today. Your first Half Marathon is one of the most important races that you will ever do, whatever level you eventually reach in the sport!
Unfortunately the chip timing system was bedevilled by exactly the same problems as when it was used at the Leicester Marathon. I encountered a lot of chips lying on the ground, and even had to chase after a couple of people to reunite them with chips that had just fallen off. I hope that the organisers of both events will take note of this, especially since the systems used in the Leicester Marathon in previous years, had a very high level of reliability.
