I had that issue too. I have solved it with checking all script mods for possible updates and updated all script mods again. Afterwards MCCC showed up and works fine again.Does anyone else have problems with MCCC menu not showing up? I checked my mod list in-game and mc_cmd_center shows up as one of the mods; both cc and script mods are enabled as well, but I can't seem to get the menus to show up either on sim, computer, or mail. Happend when I updated to the latest one.
