The first thing to try is to update your Camera RAW - here's the link;
Adobe - Photoshop : For Windows : Camera Raw 3.7 update
assuming that you're using Windows.
If that doesn't fix it you can use the Adobe DNG converter
Adobe - Adobe Camera Raw and DNG Converter : For Windows : Adobe DNG Converter 6.1 update
which will give you DNG files you can open in Camera RAW.
And there's always RAW Therapee, of course - very good but takes some learning!
