LiquidMachine Exception

Question

I am using LiquidMachine API for encryption of document. I have a ref in my project for CSharpCPAPI.dll v1.0.3182.27556. It was working fine untill i copies the solution on another machine.On the new machine, this code is throwing an exception when Iniitializing the ContentProtectionLib i .e

ContentProtectionLibrary.initialize(new ContentProtectionLibrary.InitializationArgs());

The exception is The type initializer for 'LiquidMachines.CPAPI.LMCP.LMCPWrapperBase' threw an exception

I don't have any clue as to why this exception is coming up. both machine are same. and I don't have documentation for this API also. Could any one help??
