[Rednet][Lua] Rednet Mail-System

Hello EveryBody!!!
Im trying to make a wireless rednet mail server and have a problem. I've downloaded a code from NitrogenFingers:
but when im trying to send a email it times out and will never send. I've read the README.txt files and browsed some files but nothing works. I've read the code and edit the modems to the correct side, But im still stuck.
Any Ideas??
Thanks, DJ

The script has its modem side set to "left". Is your modem on another side?

As i said in the original post, i edited the code to the side of the modem in the code.

I would Reccomened running the code or watching the video:http://www.youtube.com/watch?v=BA0JX8uYLAA
but it works on his video?
but im running computercraft on tekkit 3.1.2?
Do i have to run it on 1.5.2? i have forge installed and can install it on there

First of all, if this is on a single player world, I would recommend not using Tekkit. Frankly, I'm amazed they haven't abandoned Tekkit yet.

Second of all, I have a feeling that your problem is distance. Wireless modems have a very limited range. Try again with the computers really close together.

What version of ComputerCraft is even in Tekkit 3?

I think its 1.3, But ive downloaded it for 1.5.1 and Had them close together. so it's not distance
