What operating system are you using? Have you manually gone to Windows Update or the App Store to download all of the latest updates, including those that do not download automatically.
How much free space is on your C drive? When did you last run Disk Cleanup and Disk Defragmenter on your computer? A hard drive with limited or fragmented space can choke some intensive programs.
Have you tried launching the program while holding down the Ctrl+Shift+Alt keys on the left side of your keyboard to clear your preferences?
Have you tried uninstalling the program, running a registry cleaner like CCleaner and then reinstalling?
