Commercial license, but showing academic license

I work for COWI where we do have license for PLAXIS3D. When I am opening a file in the shared project folder, it opens up and I can run it. But when I am copying that PLAXIS 3D file along with the associated folder to my local hard drive and trying to run the PLAXIS3D file, it does not show me the model, rather there is water mark of Academic license everywhere in the screen. Why does it happen?
