Zgemma S2- Open Atv 5.1 prob installing Linux addons

Hi all

Ok so I downloaded the Open ATV5.1 from their website. The problem is I can't install LinuxSat addons on the sytem. I put it on the USB and it doesn't install even though it says it does. I tried using FTP, that doesn't work. Does anyone have any ideas please?

Tks

Thanks guys. I actually got it through the box itself. On the menu I went to TS PANEL and then addons. It works fine now.

Another question though where can I get the original Open ATV 5.1 skin from????
