The files were supported when I created the project on a college computer in a previous version of Premiere in 2009. I have tried downloading quicktime and restarting so far.
Installing Quicktime, usually but not always the latest version, is supposed to permit editing MOV files
But, exactly what is inside the MOV file, and what camera did you use?

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037
Report back with the codec details of your file, use the programs below... a screen shot works well to SHOW people what you are doing
After installing the latest version of Apple's QT Player, did you reboot the system?
QT Player should install most common MOV CODEC's, but for them to show in the system (where they are installed), one usually needs to reboot.
