Error occurs when adding the USBHost (premium) module - "A required library could not be found."

I just want to say that I reinstalled the driver and the following are exists:

C:\Program Files (x86)\GHI Electronics\GHI Premium NETMF v4.2 SDK\Assemblies\GHI.Premium.USBHost.dll

C:\Program Files (x86)\GHI Electronics\GHI Premium NETMF v4.2 SDK\Assemblies\GHI.Premium.USBHost.xml

And I think it happens only with the usb module.

EDIT: Created a new project just to check and there was no problem adding the module, apparently only on my current project.

@ andre.m - Spider. It worked before and it’s working now on new project. it’s 4.2

On my current project, i used this module and then removed it. Maybe something went bad?

Ok, I managed, I deleted the spider mainboard from the diagram and returned it and now it’s fine.
