Have you logged onto ticketmaster? Mine showed immediately in the appI did have a code for Knebworth today, but I couldn't get tickets. Only special packages were still available.
A friend had a code for the subsequent sale. He was able to pay for 4 general admission tickets but didn't receive a confirmation email... we've been in uncertainty for 2 hours already. The money has been debited from the account though! Hopefully those tickets will still go through!
My conclusion about this system: Just go back to the old system.. I have rarely experienced so much stress for so long over tickets.
Got another code for tomoz so deciding whether to do double duty
