I've been using DVDShrink for a while. All of the sudden, DVDShrink started causing a stop error. I haven't changed it in any way. It happens when I try and open DVDShrink. When I double click on the icon, the screen goes blank and the computer reboots. After it reboots, it says your computer has recovered from a serious error. I've tried uninstalling and reinstalling from different sources and it doesn't work. The only way DVDShrink works is if I use it in safe mode. How can I fix this?
