Using JNI4Net to call C# dll

I am working on integrating a third party DLL with our software(in Java platform). Followed the steps mentioned in https://www.youtube.com/watch?v=8OoSK_RWUe4 and encountered an error during running proxygen.exe. I tried searching for resolutions for 2 days and couldn't find any useful. (http://www.codinghouse.org/calling-net-dll-from-java/#comment-395512) (https://groups.google.com/forum/#!topic/jni4net/43HbWrRvZRA)

Below is the stacktrace

D:\jni4net-0.8.8.0-bin\bin>.\proxygen.exe "D:\VBProjects\FirstCsharp\helloworld\helloworld\bin\Debug\helloworld.dll" -wd "C:\workspace\CSharpJavaProject"

Proxygen must be run as trusted assembly! (shared drive could cause the problem)

System.TypeInitializationException: The type initializer for 'net.sf.jni4net.proxygen.model.Repository' threw an exception. ---> System.IO.FileLoadException: Could not load file or assembly 'jni4net.n-0.8.8.0, Version=0.8.8.0, Culture=neutral, PublicKeyToken=134a23405600bab4' or one of its dependencies.

Operation is not supported. (Exception from HRESULT: 0x80131515) ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.
