Error using SmartCard and STS Sample

I am trying to use smartcard with STSSample with no success. I created a sample certificate usingmakecert tool. So I installed it in smartcard. When I put the smartcard on the reader appears a dialog to confirm certificate installation and installs the certificate inCurrentUser\Root and CardSpace cannot find it because seems me that CardSpace only find inCurrentUser\My (Personal). If I copy or move the certificate toCurrentUser\My, CardSpace find it and request me a PIN and the reader is accessed (LED work) and for finish tell me that an error has occurred. Find the error details in Event Manager I find the following:

An error occurred when communicating with the Windows CardSpace service. Exception of type 'Microsoft.InfoCards.CommunicationException' was thrown.

Inner Exception: Internal Error

Additional Information:
Microsoft.InfoCards.CommunicationException: Exception of type 'Microsoft.InfoCards.CommunicationException' was thrown. > System.ComponentModel.Win32Exception: Internal error
at Microsoft.InfoCards.NativeMcppMethods.RpcCryptoDispatchRequest(IntPtr hIdl, String contextKey, String requestName, Byte[] buffer, Int32 index, Int32 length)
at Microsoft.InfoCards.RpcCryptoRequest.Process()

I am using ROCKEY200 smartcard reader:http://www.ftsafe.com/product/show_product.php?id=21&type=300000&section=3

Could anybody help me about this?

How can I set to the certificates be installed onCurrent User\My?

Thanks.
