Hi,
Yes im using the latest drivers as i only bought the card a week ago, ive also tried it in a toshiba laptop and it works fine, i think it has to be something to do with the pcmcia controller that is installed on my sony vaio, its a richo R/RL/5C476(ii) pcmcia cardbus controller, i wondered if you knew any compatability issues with this card.
anyway i have included a capture file for you to look at, following the error code it just tells me that it is because the card isnt istalled properly but windows tells me it is.
