I use adobe bridge and bridge downloader bring in my images, i shall look through my cd's to see if I got it somewhere, not sure if its a free download but you could always try the trial version to see if it works.
I use a mac and CS3, i was lucky enough that when my dad bought it for his business he bought the multi user version
. I dont have problems opening images, but I did disable i photo import.
You could try this method which also works for me:-
1. put card into your card reader, or plug in your camera
2. disable any autoimport, just click red button
3. make new folder on desktop (i call my raw files)
4. open card folder from desktop and drag new file into raw floder
5. when using elements (or your raw converter) use the open file and search for your raw folder
6. open and images should thumbnail
