Chance to recover images? Removed USB cable during transfer

I did use Cam2PC version 4.33 to transfer some images from my Canon Ixus 430 to a computer with Windows XP Home. I made a mistake and removed the USB cable during the transfer.
The images are already deleted from the camera and they do not show up in the folder on my hard disc, in which Cam2PC normally stores my images.
Are the new images gone or is there a chance that I can find them somewhere in a temporary folder on the hard disc?
Thank you!
Sandra
