Same message here. Got through to the selecting tickets page (eventually) entered code, I'm not a robot etc. etc., and then the "sorry no tickets available"
I find I'm getting really frustrated these past couple of years with my distinct lack of success in ever getting tickets for concerts on-line. I used to have a good success rate' but know it seems I never succeed despite having a very fast broadband speed and always being on line to the second. This morning when the View Tickets icon popped up at 9.00 am I must have pressed the button within micro seconds, which still was not quick enough apparently.
I shall try again Friday, but don't hold out much hope.
