Can I use the design I bought also in OWN3D Pro?

At the moment, this is not possible. We are working on a solution for the future. The OWN3D online shop and OWN3D Pro are two different platforms. Overlays which were purchased in the OWN3D.tv online shop, are not linked to OWN3D Pro. That means you cannot import an overlay that was purchased in the OWN3D online shop into OWN3D Pro.
