It appears the festival is already sold out, within an hour of the passes going on sale. That's the quickest sell-out I recall. It's not surprising, as mentioned in the previous post, "never underestimate the power of the radio." There's always a chance the website malfunctioned, so until you hear official word in a press release, it doesn't hurt to keep trying.
UPDATE: As noted in the comments section, Sasquatch! is officially sold out. DO NOT ATTEMPT TO BUY TICKETS FROM SCALPERS. Scalpers take advantage of people freaking out about not getting a ticket, so this is the worst time to attempt to purchase a pass on craigslist. Be patient. There are plenty of good people out there who are not looking to screw you over to make a couple bucks.
