GemXpresso JCard Manager session authentication problem

Question

Hello!
First of all I am new in Java Card Technology and I am trying to explore the
JCard Manager environment. I am using GemSafe Xpresso Cards.
My problem is that I cant create a session between reader and card in one of my
cards. The trace in this card's authenticate prosses is:
Default key file URL: file:/C:/Documents%20and%20Settings/user/GemXpressoJCardManager/keyfiles/jc2.2.1%20-%20gp2.1.1/default.keys
Select the Security Domain
->  00 A4 04 00 08 A0 00 00 00 18 43 4D 00
<-  61 1B   [Normal ending of the command with <27> bytes of extra information.]
key set 0 (Card Defined)
Initialize Update
->  80 50 00 01 08 00 01 02 03 04 05 06 07 (00)

Card info KeySet=13
(SCP 01,implementation i05)
Command Exception on command: Authenticate. authentication failed: The card cryptogram is not verified.the other cards pass this procedure successfuly showing the message:

A Card was removed from the terminal: Gemplus USB Smart Card Reader 0 from the slot: 0I think that the card came this state because my partner to this project was
issue a command by accident, and now he can't remember what he done.....
I suppose I have to change the card's KeySet from 13 (D0) to -1 (FF) but I don't know how.
Does anybody knows what i suposed to do and fix the problem??
Thank you in advance for your help, Bill....

Answer 1

Lets see... First of all thank you for the reply. Also I forgot to say that I use Global Platform 2.1.1 cards.
I understand that the initial keyset has been changed and I can't turn
back to keyset -1. Also my partner said that he don't remember to issued a specific command, but the only thing he remembers is that he send
an (unknown for him) APDU to the card, from the SEND APDU panel, not very wise move.
So he did not create a new key set, as I understand. I use the GET DATA command with Predefined Taq set to Key Information Data to retrieve the
informations you told me but the answer was
Get Data
->  80 CA 00 E0 (00)
[ERROR  ] <-  6A 86
[ERROR  ] <-  (ISO 7816-4) Wrong parameter(s) P1 P2 (Incorrect parameters P1 P2). So? what I can do now?
Thank you again in advance.... Bill
