You need to give us more information in one post otherwise this game could go on a long time.

1. Have you tried rebooting?

2. If yes, what are you running Node-RED on? What version? What version of nodejs?

3. You mention 2 different nodes `Node-red-node-arduino` and `node-red-contrib-gpio` but only talk about one window

> the window prompts cannot read property 'on' of null.

So what node are you using? When does it give you that error message? How have you got the node configured?

How did you install Node-RED v1.0.1?

Have you tried reinstalling node-red-node-arduino?  
Are there any error messages when you reinstall?

I didn't ask you to uninstall it.

But I don't have time to keep up with the same issue in multiple threads. Good luck is finding the solution.
