Vizard with Vuzix VR920 headset

[Darkmax]

hi i'm having trouble with vuzix vr920, i don't know if something change because im trying to load icuiti plugin and it tells me this error:

** Loading hmd_vuzix.py
************************************************** ****************
** ERROR: Failed to load plug-in: 'icuiti.dls'
** ERROR: Link failed (source linkable is invalid)
Loading File: gallery.ive
** Load Time: 0.80 seconds

my code is this one:

import viz
viz.go()

#Add icuiti sensor
icuiti = viz.add('icuiti.dls')

#Link sensor to viewpoint
viz.link(icuiti,viz.MainView)

viz.add("gallery.ive")

PD. I'm using vizard 3.18
