No products being showed in VM-Products while set to Random

[Kupernikuz]

Does anyone have expiriences with the VM-Product module, using it to show random products?
I'm on Joomla 1.7.5 runing Virtuemart 2.0.0.
Have filled in a few products, and want to set a module on my page, showing random products, but the module sows nothing.
If I choose the module to show Featured products, it will show those products that I have set to be featured, but for that I use the "Featured" module.
If I choose the VM-Product module to show "Latest Products" no products being showed either. If I choose to show "est Sales" it is ok, showing the best sellers.
But the Random Product and the Latest Products don't show anything.

Are there anyone that has a hint to what I can do to get it working?
