A .net constructor throws an exception. Assembly problem?

Hi!
I am new to this forum and LabView in general.

 

I am having a trouble with an .net constructor. I am calling a .DLL file with the Constructor Node. I get a "Error 1172....A .NET exception occured in an external assembly." I have installed the .DLL file to the GAC and I have verified in the View/.NET in Assemblies tool that the .DLL file is linked correctly.

 

My goal is to use a function called groupCommand() that I get from the SMBusAdapter constructor. What is interesting is that I have got other functions from the same .DLL file to work.

 

Can someone please give me some guidance. I attached the files I am using and there is also the GAC installer.

 

(I am running LabView 2011 on Windows Vista)

 

Attached files:
TIDP.SAA2.dll - the .dll file

group.vi - the file where the problem is.

send_byte.vi - A file where I got the .dll file to work with another function.

 

Thanks.

A constructor should be called only once.

Of course, but I am only calling the constructor once.
