[API] Simple Add-in Error 'A command definition with this id already exists'

[Anonymous]

Hi, I am having the following script (which I already run a couple of times before). Now, whenever I run it again a get the error (shown below). I assume there is some small bug in the stop function, but I cannot really find it. If anyone can help, I would very much appreciate it!
