One other thing... if you can't find your toolbars list by right clicking on your other toolbars (though you really should be able to access it this way), try alt v for view, and your toolbar list should also be there. Make sure your menu bar is selected with a checkmark. If it is, but it's still not visible, maybe you dragged it to somewhere else on your toolbar area? I would uncheck your other toolbars, see if you can 'find' your menu bar, drag it to where you want it, then add your other toolbars back in. To do this, make sure your toolbars aren't 'locked' (also on the toolbar menu).
Of course, more than likely, that's not the problem anyway.
