The Adobe Acrobat 9 Pro that came with my Adobe Design Premium CS5 package no longer launches.  I haven't made any changes to my computer and am using Windows 7 Professional.  I've tried to repair and modify from my computer's Control Panel and nothing worked.  I've also tried to download the updates from Adobe by clicking on the update for Adobe Acrobat 9.5.5. The update appeared to install properly but the Adobe Acrobat 9 Pro failed to launch.  Let me know how to fix this.
