Photoshop Raw Stopped Working

It says version 6.6.0.261. The camera I'm using is Canon Rebel T1 (I think). I've had both the camera and the student photoshop version for 6/7 years, nothing has changed. It's just that one day I opened up the program and tried to edit my raw file (CR2) and it doesn't recognize the file. I've edited raw files for years. It does recognize jpg. I get raw files from my Canon S120 point and shoot and those are the ones it says is not compatible but I know I've edited those before. It seems I can open older raw files but not newer ones taken but neither camera has changed. The windows file recognizes it as a CR2. When I click on updates it does say there is a photoshop camera raw update available (6.7) so I go through the update process and it says there was an error downloading the update (happens every time). Any help you can give would be great. My stack of photos to edit is piling up! Thanks!
