I've been using Microsoft Office (mainly Word and Powerpoint) on my 2013 Macbook Pro for a long time with no issue. I recently upgraded to Yosemite, and now any attempt at starting one of the Office program results in the program freezing out and not responding. I've updated Office to version 14.4.7 to no avail, and ended up reinstalling the program multiple times. Now it won't let me update to 14.4.7, giving me a message that the correct version of the program I'm trying to update isn't located on my hard drive...I've checked and deleted any duplicate fonts, and verified the other font permissions, but no luck! Help me Obi-Wan Kenobi, you're my only hope!
