Be sure you removed any previous version you may have had on your computer.
Reboot your computer.
Close any programs that may be runing.
Try reinstalling or download again as it's possible you encountered a glitch.
Want to see what's runing each time your computer is on?
Click on START> RUN and type in MSCONFIG and click OK
Then click on the STARTUP tab. All items with a check in the box is an item
that loads/runs each time you boot up. Obviously, uncheck any ones you don't want to load/run. You'll be surprised how much resources are freed up with this method.
Good Luck,
