We want to sincerely apologize for the technical issues that occurred Saturday night with the Invicta fights. The problems were due to payment processor server that was in beta -- we have identified and resolved the issue and we don't expect this to occur again in the future.
We are issuing refunds today for all ticket purchasers, although it could take up to a couple of days for the funds to to appear on your account statement.
Again, we're very sorry about this. Ustream is committed to customer satisfaction, both in resolving the problems from this event and avoiding these kinds of issues in the future.
