You haven't provided any error messages from HotKeyNet, so there's not much I can do to troubleshoot. But HotKeyNet scripts aren't plug and play, they will require some configuration as explained in the guide I linked.

If your toons are running off in different directions, I would guess you are using the arrow keys to move, which is how that script is configured. Arrow keys are not usually used for normal movement, most people use WASD and reserve using the arrow keys for times when the slave and master both need to move out of something or across a phase line.

I can't address any of your other issues or be more specific unless you include the error messages you are getting.Everything HotKeyNet does or tries to do should be listed in the "Actions on this PC" window. Ensure that the "Show" box is checked.
