Well, I needed the skin and saw it for sale on vBMechanic.com. The shop isn't closed, just the demo isn't working. After payment however nothing happened so I send a few emails without any response and then decided to download the skin from jotin.nl/forum/
Again, the shop isn't closed you can just pay as usual for the skin but if you want the skin you will have to download it manualy.
Best Regards,
