Can anyone please tell me why the HSS feature in my home install version is grayed out? I am not getting any response from tech support email and chat requests. It works on my work PC so I'm wondering if there is a restriction like not being able to post G-Code. Is there any information on what restrictions the home install version has?

I'm still new to this CAM software and have been learning at home every chance I get so it would help of I had an idea of what to do here.
Thanks.
