I WAS scanning, saving, and opening images in Irfanview without any problems, but lately I keep getting the message shown in the image below. I can still open the previously saved images, but I can't open any newly saved images.
The way that I'm scanning is opening up PaperPort (my scanning software), clicking on the file folder for "My Cards," and then scanning. There is no option given for what format I want to save the image under.
What am I doing wrong? How can I resolve this problem and prevent it in the future?

Thanks so much!!!
