Hey there

Bought a Canon 1100D back at Christmas time and installed the software provided with it. Sensor is in need of a clean but until such time I was having a play with the stamp tool in Digital Photo Professional, stamped out the blotches, really happy with it but I can't save

Ummmmm help! I go back to the original image then go tools --> start stamp tool and it opens the image that I've modified but when I go to save it the save selection bit in the drop down menu is greyed out.

What's going on? Does DPP need to be registered to activate certain features?
