Sorry you are having these problems. If you start with a motion project from the project browser then you should be able to proceed as I outlined above ie use the Publish Template from the File menu. If you start from a Motion Template ie Title, Transition, Effect or Generator then use the save item from the File menu. In all cases the dialog box which appears allows to create a new category. If these options are grayed out you have a problem with your installation. I would first trash the Motion preferences "com.apple.motionapp.plist and
com.apple.motionapp.LSSharedFileList.plist". You will find these in User/Library/Preferences. Then relaunch Motion and it will rebuild these files. If that doesn't solve the issue I would reinstall Motion. Good luck! Some folks in FCPX forum have had trouble with MacKeeper causing grayed out menus. Do you have that software installed?
