50D RAW photoshop help

Got a new 50D in November.couldn't load raw images into photoshop cs2.got enough money to get cs4.still can't get raw images to load from bridge.i can get a raw image to load from canon digital photo professional to photoshop,but this is kinda a pain.any help would be appreciated.photoshop keeps telling me it's not the right kind of document

You probably need to download and install the latest version of Adobe Camera Raw (5.6) which supports the 50D.
You can find it here.

thanks John.worked like a charm.you would think if you buy a new software program it wouldn't need to be updated the first day.now I have to relearn a new workflow procedure with lightroom 2 and cs4.wish me luck as I've been stuck with my 20D and cs2 for years
