05:35 PM ET 04.04 | The last time Invicta FC did a pay-per-view, Ustream couldn't handle the traffic and its CEO Shannon Knapp had to refund its fans. However, Knapp decided to stick with Ustream for their latest pay-per-view this weekend. "If I look at it from a business perspective, sure, they screwed up," Knapp said. "But I'm taking just as big a risk if I go with someone else. I'd have to go in to them and say, we have a high volume of traffic, can you handle it? Of course they'll say they can."
