I have never had any trouble with Anydvd and Clonedvd untill the last download. And i have not added anything or took any thing of my computer. After downloading both downloads of anydvd and clonedvd my computer would hang up and as i would try to use clonedvd it would hang up and i would have to restart my computer every time i tryed to use clonedvd. To get any thing to work i had to restore my computer to the date befor i added the 2 downloads. Now every thing is working great To me it looks like there has to be something wrong with the new Clonedvd but i am new at all this.
