Cannot load the plug-in defined in...

Hello there

I am trying to implement a Studio plug-in that connects to WorldServer, and therefore references:

using Com.Idiominc.Webservices.Client;

using Com.Idiominc.Webservices.Client.Exchange;

In the file pluginconfig.xml from the Studio3 installation folder I have added:

<PublicAssembly name="Com.Idiominc.Webservices.Client" version="9.0.5290.15454" />

<PublicAssembly name="Com.Idiominc.Webservices.Client.Exchange" version="9.0.5290.15454" />

Still, the attached error message comes up when starting Studio to load the plug-in. The Studio3 installation folder also contains the DLLs WSWebServices.dll and Microsoft.Web.Services2.dll.

Any ideas would be greatly appreciated.

Cheers
