PUT KEY command with returned SW 6982

Question

There would be some other threads dealing with PUT KEY command however, my put key command failed with SW6982.
Firstly, I have done it successfully in Java and now I migrate this solution to C#.Net, I have an PCSC class which helps me communicate with the SCreader. I refered to this thread
[PUT KEY APDU|https://forums.oracle.com/forums/thread.jspa?threadID=1551395]
I implement exactly the same as I have done in Java (based on source code provided in the thread mentioned above) but failed. Here's a log file for the communication

I have replaced the values of this scripts to the java code and it produces the same values as in C# code. I really don't know why? The External Authenticate command executed successfully and I use its C-MAC to calculate to C-MAC of PUT KEY command (as detailed in EMV CPS v1.1, page 79/103).
One more thing: in the source in the thread mentioned above, I saw that in the PUT KEY apdu command, he added the value "00" after the C-MAC of PUT KEY. I don't know why?
Is there anybody experienced the same problem as mine and has resolved it? It would be very kind of you to spend a little time on my problem and advice me what to do, I'm really stuck now.
Best regards,
JDL
