License gone after update to NMS V 3.x

Hi,

 

Last week I just purchased NMS 2.x for my Samsung Tablet from the Apps store.  Yesterday I did update my apps and I received NMS 3.x  It seems my license is gone!

 

I did read already some comments on the apps store where other users experienced the same behaviour.

 

How to solve this please?

 

Thanks!
