SCardEstablishContext returns 0x00000002

Hi,

Just downloaded and compiled XPCard, and installed the component as part of a trial extension for firefox 2.0.0.6. When I perform a xpcard.establish( SYSTEM_SCOPE ) from javascript within the extension, I get a return code of 0x0000002 from the SCardEstablishContext.

Winscard.dll is OK and in my \Windows\System32 directory. I can debug the component, once loaded by firefox, but always get a 0x00000002 return code from SCardEstablishContext.

Any ideas on this ? Anyone using this XPCOM component with Firefox 2.0.0.6 ? Does anybody have a test setup they can send me ?

Thanks Sean
