First I am new to this program. However, I have great need to clean up my computer before it gets on my nerve to the point of madness. I have installed the program but it does not activate after installation. I have tried using the shortcut on my desktop and the hourglass comes on for a few seconds, but nothing happens. In addition, I cannot de-install it to try and re-install unless I start the computer in safe mode and de-install it that way. I don't know if Im doing something wrong, or there is something in my computer preventing the program to run. I have Norton Premier 07 installed, but I disable the virus prior to installation. Any help will be greatly appreciated.
