I just purchased Wildfire 4.0 student edition (online download). My problem is when I open the program and go to set my working directory the program instantly closes after I hit "set". Also I am not even able to create an extrusion or revolve. After I select extrude, I an not able to select a plane with the mouse, i have to click on it from the model tree, then when i hit sketch the sketch screen does not appear it just stays on the object view screen but the sketch icons appear. After i try this once i loose all of the revolve and pan functions in the object view. Please help
