I think something is fishy with your skin helper add-on, which version nr is it?

Need sleep now, more help tomorrow :p

I finally got it to work... I did what grimmace92 said by switching to Estuary, removing the skin helper folders.
Switch back to Madnox, then installed Marcel's repo.
Then it was using 1.1.5 but no letters would appear in the Alphabet Box, so I went back to the add-on and updated to 1.0.100 and still didn't have anything in the box lol.
I went back to the add-on and it said an update was available.... So I updated and it was back to 1.15 erm
And at last, it now works, go figure...
Anyway, thanks for the help
