Missing Buttons and Menus

Hi all,

Just noticed this the other day trying to make a part--I don't have the vent feature!! Also noticed that if I try to open up the fastening feature through View -> Toolbars -> Fastening Features nothing comes up. It is really throwing me for a loop especially considering the workstation next to mine is running just fine.

Currently using SP4.0 but downloading and installing 5.0 hoping that helps.

Any advice is appreciated!
