Photoshop problem

[Nigey]

Ok, not sure what caused this or how to solve it. When I load my RAW files to the disk and preview them in any of my previewers they look just fine but as soon as I load them into ACR and subsequently CS4, all the color (US SPELLING FOR YOU GUYS) just washes out. They are really muted? I don't remember changing anything and nothing I do to the setting i.e Color space or profiles seems to change it? Any ideas?

Ok, got it sorted now, it was ACR that was opening my sRGB 16bit images in 8 bit Adobe RGB
