Photoshop CS keyboard shortcut problem

Not a huge issue, but at work we’ve got Photoshop CS and a lot of the keyboard shortcuts refuse to work - even after I go to Edit>Keyboard Shortcuts and modify the settings. Off the top of my head, the ones that don’t work are:
Feather (ctrl+alt+d)
Hue/Lightness/Saturation (ctrl+u)
Curves (ctrl+m)

…and… ugh… I’m sure there’s a lot more, but I can’t remember right now. Strangely enough, I know that Levels (ctrl+L) works fine. I’ve even tried assigning different shortcuts to these non-working commands, but they still refuse to work.

Kinda slows down my workflow having to exit my leetz0r full-screen no-palletes-or-menubar setup just to feather a selection.

I know there were some keyboard shortcut issues with a pirated Photoshop CS version that was floating around, but I’m 200% sure they’re using a legitimate copy at work :stuck_out_tongue:
