I/O Read Error with Image Sprayer

Hi! 

I'm trying to use the image sprayer function on Corel PhotoPaint X6 (Windows 7 64 bit operating system). However, every time I attempt to use any form of the function, I get an "I/O Read Error". I'll then be notified that "There is no image list loaded. Create one using objects or load an existing CPT file." (This, btw, happens when I try to use the default image sprayers...)

I've had my project crash twice on me already this evening and I just want to be able to add a little effect to my project! Help me, Corel forum users. You're my only hope.
