I run DPP from time to time just for comparison purposes with Lightroom and haven't experienced any issues with it (version 3.7.2) so your question intrigued me somewhat. It must also be said that I haven't got Elements installed and like Chris has already mentioned, this does seem to cause problems with some users.

One other possible cause given is that Elements is somehow messing up the Makers Notes in the file although this appears to be limited to jpegs that have had some editing done to them e.g. cropping.

How do you usually import images onto your computer - does Elements do the import? To try and confirm that Elements is in fact the cause you might like to consider shooting a couple of test images and use Windows Explorer to copy/paste them into a temporary folder directly from the card. Shoot a couple of straight RAWs and a couple of straight jpegs but NOT RAW plus jpeg if your camera allows for this. Once that's done have another go with DPP.

If the problem still persists with freshly shot images you might like to try uninstalling DPP, restart the computer, download and run a very good FREE registry cleaner such as CCleaner, restart the computer again and reinstall DPP from the CD. If the version isn't 3.7.2 go to the Canon website and update DPP prior to using it. Don't forget to shut down any virus scanning application you may have on your computer prior to install.
