First file Primo is trying to open is global_cfg.zip, so if content folder could not be found, than you get this message that it's missing.
As I can see from picture in this post [Only registered and activated users can see links. ] and here [Only registered and activated users can see links. ]
On your SD card there is NO "iGO" folder, but folder content is at root of SD card.
On SD card you MUST HAVE "iGO" folder, and everything should be placed in that folder
Or maybe I'm just wrong
