i have never ever used this programe beforeProbably because you used up your trial sometimes before in the past and must have forgotten, and it still is showing you have Zero days left in your registry.
If you really never installed it before, I have no clue.
if i was you i'd forget the trial period stuff trouble you've had,and just purchase it-you'll be glad you didhow can i run a programe when thats the first time i ever downloaded it
i get the impression you are looking for free software to back up your dvd collection and don't wish to pay for it.so much for try before you buy
