Lightroom 4.4 for MacOSX

Hi,
I'm trying to import some CR2 files made with a Canon 6D in my Lightroom 4. I had to reinstall the app on my old MacBook Pro so now I've the version 4.1 that it seems does not support camera raw 9. Probably I used to have a newer version of the software that support my camera in previous installation made on other computer, but I can't resume that.
I checked my Adobe account and Lightroom 4 is correctly registered, is it possible to obtain the 4.4 version or another version that support my camera?

Thx, regards,
Gianfranco
