I've installed the Camera Raw 4.4.1 plugin, but still can't get Photoshop to open the .cr2 files. It opens other raw formats, so the installation doesn't seem to be messed up. Adobe's support page indicated that I should be able to open the XSi raws in photoshop with the updated camera raw, but photoshop says it can't recognize the specified file format. Anybody else got XSi (450D in other regions) raws opening in PS? I also tried installing Canon's utilities, but DPP crashes every time it tries to open any image.
