I seem to have lost my Add Labels Menu Botton on my Annotate Ribbon. I have tried reloading my workspace but it is still gone. Does anyone know how to add it back on?
I presume you're using C3D 2010? This was a bug in that version that was never fixed. It happens if you shut down C3D while the Annotate tab is active in the Ribbon.
You SHOULD be able to fix it by simply clicking on your workspace in the Status Bar at the bottom of the screen. If that doesn't work, then I have no idea why.... It's always fixed the problem for me.
