Hi Again!
I think there could be an element of user error going on here. Yes, when you originally posted you were so vague and it is difficult to assist you. We don't know the complete story. We can presume XYZ, but the problem could be elsewhere ie ABC.
I always use the Canon software and download direct from the camera. I download from the viewer and I see "Jpeg & Raw" on the screen. Under each photo I see CR2, Ie RAW. However, when I connect, sometimes my camera goes to sleep and I have to wake it by pressing the shutter button. On doing that I see the EOS 20D come alive. Under it I see DCIM which I open up an I see my photo files on the card, ie, 118CANON in my case. All this is in the Canon Viewer utility. I then drag the folder into where I want the photos to be located in the future and then it starts to download.
Upon completion of downloading and if I wanted to work on the RAW I then go into Canon's Digital Photo Professional and open the photo and I am in RAW. If you say you have downloaded the Jpegs, you should have downloaded the RAWs also. I do split my files into Jpeg and Raws for convenience.
You do not say what type of PC you have? XP, or like myself MAC or Windows 98. If you are in doubt about the software, I would download it to your work PC and if you get the same results, then you may indeed have duff software. However, the same could still be applied, as it could be user error- you could be doing something wrong afterall. What Canon viewer do you have, on my MAC I use 1.1.0.16 and it works fine. I have no idea what version you should have with Windows.

PS, try and do a search for ".CR2" files and see if you can find some on your PC.
