The start-up message is normal.
If you are using a Sandisk brand card, check “Settings”/ System Info" and check if the card is being read by the Express.
If your card is not a Sandisk brand, then your 4gB card may not work. See the attached thread. Sandisk knows about problems with PNY and Kingston, most likely other brands have problems with the Express. Sandisk doesn’t seem to be too worried about the problem, they haven’t put out new firmware to resolve the problem.
