Wolvesphil this behaviour unfortunately happens sometimes on a reinstall especially when GUI settings get changed. Re do the whole smart playlists ( when you say you don't see the manager its in the settings & widget settings ?)
Another idea would be to redo the skin from scratch as at present your copying of the back up is having an issue with something in the skin & hence. Otherwise get a debug log & put it here.

I have now rebuilt from fresh but still unable to access smart playlist manager. My steps are settings - appearance - edit main menu - up (for general options) - it should be here? i have also tried widgets: add-on settings

My log is here

you have script.playlists addon installed ? without this - no smartlists
the help page on skin settings with this info will be updated soon

i am fighting with jarvis and complete fresh madnox atm ... so be patient please
