Raw files now working in CS4

Well for some how my Raw files will now open in Photoshop CS4. Don't know if it is because I'm using the camera software to download off the card but that seems to be the only thing I can think of. I'm running CS2 at home and even though I have updated the camera raw plug it will not  work but used CS4 in class and it works now. All I can say is yay. Now its time to go get some blank disk so I can clean out my portable hard drive. Even after editing and cleaning out files and bad pics I still have eleventy billion pics taking up space. So easy to get carried away using a digital camera.  I've been putting it off but time to clean house or im gonna run out of space for all the wonderful fun pics in my future. There out there calling me to take them I can hear them now while I sit at my desk. Well time to go get some work done. later all.
