Override errors?

Since I'm done with the abDrawCards, I finally was able to perform a complete update.
On a number of Gui_ classes, I'm now getting these errors:
"The method getCard() of type GuiDisplay2 must override a superclass method"
Am I now missing something new, or are these errors part of the work in progress on the card images?
