Empathise entirely with you
@Paul B regarding the ticketing process. We experienced exactly the same, on my laptop and Mrs L's PC. Exactly as yourself we were asked to update our profiles despite having bought tickets to the Exeter game only a week or so previous.
Fortunately, and following a suggestion from a poster on here, I contacted the ticket office and we were put on the waiting list. Yesterday, bingo! Two tickets duly materialised. To say the mood lifted would be an understatement. Even the mid-week no alcohol rule was swept aside (with some vigour!)
I've posted my thoughts on the system elsewhere but, something is not right, it just doesn't come across as being a robust and reliable system.
