1. i have no idea...
2. you have to select vertex mode(in the left side panel) and select the vertex first then move it...and moke sure you in move mode...its not like 3dgs where you can click a vertex and move it at the same time... its accident proof...sorta. Im using cinema 4d atm as well and loving it..heres some of my recent render(just got c4d on sunday)
