Invalid Invoke Node

[sgm20]

I am trying to send a command to a Physical Property Measurement System made by Quantum Design. To send the command, I am using a sub VI called "SendPPMSCommand". This sub VI uses an invoke node to send the command using .NET. Currently, I am facing an error that the method is invalid for the class. It appears that the method does not exist for this class. I am not sure why the method does not exist and I have checked all the available classes but can not find the method. Do I need to add additional classes that are valid for this method or do I add the method to a class? For either case, how would I go about doing this?

I have attached the sub VI that is causing the error.

That seems more like a question for Quantum Design... I'd contact them, to ask them why there driver isn't working for you.

Thank you for your reply. I have reached out to Quantum Design and they are looking into the issue. I will update with what they find.
