I am using an older version of photoshop (cs2). I used it yesterday and everything seemed to be working fine. Today I opened a document that was primarily all black and gray. The color picker won't allow me to choose any other color than grays. The image is not in Grayscale (it is in CMYK), the Channels says CMYK.
I tried opening other images that I've opened before with no trouble and they are also gray.
What did I do and how can I fix this?
Thanks
