[francesco.alett]

hi! i have a an emagin z800 3d visor and a polhemus tracker too; both are working (can see the desktop in the eye-screen an so on...) i'm trying to run the script as you suggested, but i read this error message in the output box when launching:

polhemus.dle Polhemus Extension
** ERROR: Failed to connect to a Patriot/Liberty: Device not found
** ERROR: Failed to create extension sensor with polhemus.dle
** ERROR: Link failed (source linkable is invalid)
emagin.dls eMagin v2.0
** ERROR: Could not connect to eMagin device. Error: 80000017
** ERROR: Link failed (source linkable is invalid)

could you help me please? thank you very much
