Ok thanks, so it's via Sportshub Tix then... well that page got problems. Cannot even register an account, tried different browsers already. After submitting the form, got an application error: the page requested is not available... (even if I try to book for another event other than u2).
Then, when I try again, it says account already exists. Using that account & password, cannot login because it 'does not pass security requirements'...
