TouchDesigner Operators don't show

Hello, as from instructions (nuitrack-sdk/TouchDesigner at master · 3DiVi/nuitrack-sdk · GitHub) I’ve downloaded and copied the two .DLL in the “plugins” folder, but when I launch TouchDesigner the TOP and CHOP operators are not there, and the provided sample .TOE give the error “Error loading network. File may be truncated”.
What should I do? Should I download and/or install something else to use Nuitrack in TouchDesigner?
Many thanks

Hello @DanieleSuppo
Sorry for the delay.
What version of Nuitrack and TouchDesigner are you using?
