Player options disabled - how to activate?

Hi there,

Using Cap 7. When I add a TOC to a project (any skin) these options are not available on the player (greyed out):

• Play/Pause
• Rewind
• Forward
• Back

Also when I try to change a skin via the Skin Editor it renames itself and adds "modified" to the end, eg City Night (modified) or CoolBlue (modified).

My guess is I have set up something wrong in preferences somewhere, but have no idea how to fix this. How do I activate these options? 

Any help would be appreciated.
