Cannot Access Equations Dialog Box

Hello,

I am attempting to use the equation editor. When I click Tools -> Equations, or right click the Equations folder in the FeatureManager, most everything greys out like the dialog box should be up. The equation box is nowhere to be found.

I am unable to do anything else until I press escape.

Any help to locate the equations dialog box would be much appreciated!
