JP1 Remotes

I've tried to do that but when I entered the code it gives me a yellow error.

for instance c1818 n2003 etc. is this the way the code should be added ?

I've tried the different methods on this forum the most recent i saw was to download the file directly to the folder but when i run the sling box program there is no amino in the brand area am i just doing it wrong.

please help..
