As I recall, when Poser Pro 2014 GD was introduced, you were allowed to use it offline but you needed to be connected about every 6 months to renew your license. I don't know what the permanent licenses allow and for how long which reinstallation a very tricky issue. I am not surprised that SM decided to extend that feature into Poser 11 rather than kill it when it became an outcry with the Game Developer.
