This happens when the skin.xml that you refer to in your scripts is using the old system. 1. Just backup the innerspace folder and reinstall everything from scratch. Make sure to use only the new versions of kbot, vga, and vgcraftbot that can be gotten through svn. That should clear it up.
Just make sure that you stop using the old skin.xml and dont just copy them back in when you are moving olderscripts back in your folder. Also dont run the skin.net file anymore. That will mess it up.
