Parallel/rednet script not working. (not solved)

Code and description; I hate repeating myself. Check the paste :D/>/>

Basically, I had a go (several gos, actually) at fixing this and I'm really not sure what to do. If anybody could explain why this isn't working (and more to the point, how I'd fix it), that'd be great, as I don't know much about coroutines etc.

The server works, so I didn't include it.

This whole thing is supposed to require as little messing around from the client program as possible.

This is a private paste

Gah, that makes a lot of sense, Pastebin… anyway, fixed the permission issue - script issue still persists
