Reply to Crane Hardware gone bust?

I bought the Crane Stand Pro (from DJ TechTools Shop) in May 2012 only for it to loose one of the sprints (holding one of the two levers) after a few dj-gigs. So I contacted Crane Hardware in June 2012 to get the sprint replaced. As I live in Sweden they promised to send it via their Swedish reseller. Then nothing - now they don't respond to my (or the resellers) e-mails. I just took a quick look at their own web shop and found out that all their products are "out of stock".

Have they gone out of business?

PS. I also send an e-mail to DJ TechTools support a couple of weeks ago... No respond.
