3) open filezilla on your computer/laptop and type in the zgemma ip address in 'host'
4) type root in username and click 'quick connect'
you'll see zgemma's folders open on right hand side
5) on the right hand side, scroll down until you see a folder called usr
double click it to open it
6) find a folder called keys, double click to open it
in here is a file called newcamd.list, the line needs pasting into this, so right click it and choose view/edit, (filezilla will ask what you want to open it with, choose notepad!) paste your line in and then close it
then on zgemma remote, go to softcam panel and restart the mgcamd softcam by clicking green button
