Card slot won't read p2 card
have you thought about restoring your system, to an earlier point.
before the problems occured, with your software update.
also if this fails, or you are unable to acheive this.
check in the device manager, to see if you have any yellow exclamation marks, next to your device.
you may need to re-install the device/driver for your card-reader.
