I have down loaded a trial version of photo shop CS6 but can not open NEF files from my Nikon D3200 or find compatible plug in's for my xp computer to make it all work. I have tried the on line help centre but they were not very helpful, said I need to contact Photoshop I'm not very impressed with this, the Serif PhotoPlus X5 I have been using works with all files! I have been told Photoshop is so much better, well I am not impressed!
What version of Adobe Camera Raw do you have? did you update to 8.3? In fact apply all updates under Help > Updates.
Edit: Adobe Camera Raw only goes up to 8.3 under Windows XP.
Also Nikon Transfer has been known to prevent raw files from opening up in Photoshop. Try copying or reading raws off your SD Card via Bridge.
