I also reached out to the people of Carpe Iter, here i post their reply
We have never stated that a DMD2 Beta would be included in the tablet order. Only the DMD2 was preinstalled on your tablet obviously until you attempted to update it to the DMD2 Beta. In fact, the DMD2 Beta is a completely different app that we never provided or had anything to do with. We can not provide any DMD license simply because we don’t have one. You might ask DMD if they would help you.
