Can someone help

I'm new to this. I was using beetv forever, we know to that. I downloaded Nuvio and got torbox, some how I was able to put torbox on Nuvio, but I touched something and I don't remember how to get it back on. I'm on the add-ons screen but I don't remember where I got the address. Looking on torbox is crazy, I couldn't find anything there. If you can help me, thank you
