I have exactly the same problem. Used it for over a year on desktop & laptop with no problems. As I clicked the icon to open it the other day, the hour glass stayed on for a couple seconds, then nothing. I went to "Add/Remove Programs" & removed it. I re-installed it & removed it 3 times, & the last time I tried to re-install it, my CD Rom drive won't even notice it's there. Very frustrating.
I called MS Tech support for help, & they said they quit helping on that version last year in October, & I should "buy a newer edition". I still have a 2002 version that worked fine for 7 years with no trouble. Is there "planned obsolescence" on software like an incandescent light bulb?
MS has lost all my respect. I would never make anything that breaks down after a short time & not have a reasonable explanation for it. Email wehelp@microsoft.com & let them know what happened, they need to offer a fix!!!
