Danny Haley , This info. from HP support. The message Invalid card data appears when the calculator is not able to properly read data on the plug-in card. The card may not be correctly installed, or it may not be initialized. The trouble shooting link#1 below describes how to resolve this. Link #2 also has info. to share. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
