Hello @drfrag, Jason is correct, the add-on will not work for XBMC 13. I was like you with my system all set up how I liked it. But took the leap into the Kodi 15, after a while you get use to setting everything back how you had it and it becomes second nature.
Thanks for the responses :)
I installed Kodi and the bigbox add on now works perfectly. Most of my settings were auto-migrated over so it was a lot less work than I expected.
Thanks for the kick-ass addon!
