    Lightroom 3 stopped importing CRW2 files


      I have a Canon 5d MarkII use a Mac and  have  I used Lightroom 3 with this camera flawlessly until last month.  Suddenly it stopped importing my CRW2 files.  I have taken my card to another location and can import into lightroom 3 on a windows machine.  I  have disabled some security software, renamed catalogs and downloaded a new DNG file.  I am at a loss.  Should I simply reinstall lightroom?
