A bit frustrated newbee her… I have downloaded gen3. And put the gen3 phyton file in my .blender scripts folder. I did the same with the gt folder. But when I open my blender and go to the scripts window, I can’t find anything under Misc. I guess there is a vital stepp I have missed?
I believe you need to click the ‘Update Menu’ at the top of the script menu after you add scripts to the directory for them to show up in the menu.
Also, should probably ask this in one of the support forums. 
thanks Was not sure where to put it so it just ended up here. Sorry:o But it seems it became ok by it self. Was away from my computer an half hour, came back and there it was… Don’t know what happend:)
