Look I do it with Lsslider but it should work with Lsxcommand also.
No need to *NetLoadModule lsxcommand-19.2 any more. (Its allready on your mods directory (unless you want it to be visible at start up).
Look in your mods directory an see what you got for lsxcommand there(version), and use that, once you got it working you can change version if you want.

just call this bangs with the complete path(for your pc)on your hotspots actions :for example:
!ReloadModule c:\litestep\modules\lsxcommand-1.9.2.dll (to show)
!unloadModule c:\litestep\modules\lsxcommand-1.9.2.dll (to hide)
should work.
