Adobe Acrobat X Pro (installed with Creative Suite 6) not working (MAC)

Hello,

A user in my office who is on a Mac (the only one) is having issues with the Adobe Acrobat X Pro that was installed with Creative Suite 6. She reports that it was working normally until last Friday. When she tries to open a PDF the Adobe Pro stops responding and have to use "Force Quit" to close out the program. If she tries to open Adobe Acrobat from the menu, she receives the typical start window with options to open a previous file, create new PDF etc., but when any option is selected nothing happens and Adobe doesn't load. Has anyone else run into this problem? and or have any suggestions. Want to check before attempting to uninstall and reinstall Adobe Acrobat X from CS6.

Thanks
