"application isn't running" error

I was running a script to activate itunes, and nothing is working anymore, it just say “application isn’t running”. I have tried every command…quit, launch, ect. Same error. What is the deal with this? Never happened before…weird things are happeneing on my computer.

Restarted your computer yet?

Maybe you ran system updates and updated your version of iTunes

Yeahm that was weird. It worked after a restart.

Most things do.
