As stating on their website:
It’s been an incredibly tough few days at WooThemes, for ourselves and a lot of our users trying to use our services. We were hacked, and badly. Our lifeblood, the WooThemes database, and all the content on our server was deleted. Not only that, but the backups were deleted and all traces of how they got onto our server too. Leaving us with scraps to work from in re-building the mothership. Source: http://www.woothemes.com/2012/04/wer...e-and-kicking/
