V7 Can't Do DXF Regions?

So, I need to import DXF, STL, or really anything for my machine region (otherwise I will have to use the polygon tool and spend literally hours trying to draw it by hand). It seems like this is no longer possible in V7, which is what I downloaded when I bought my Nomad, and did not necessitate a product key to use. Now I’m trying to downgrade to V6 so I can import drawings to define my machine regions and it’s asking for an activation code. I don’t recall receiving an activation code with my Nomad.

Any ideas? Thanks.

You can e-mail in to support@carbide3d.com w/ your purchase information and the e-mail you used to buy your machine and we should be able to look up your serial number and send your activation code.
