I installed SW 8.0 in my notebook. minimum requirements areachieved, only video card is low level. Program start ok, but if Itry to extrude a simple sketch (a circle) the following faultappears: "in the sketch zero dimensions elements are present". isit possible it depend on the graphic card or is it a wronginstallation or whatever?

n.b. also if I open an exinsting file (for example a tutorial file)it's in a errore state

thanks in advance
