If you have an error in the program it can. Are you running AnyDVD also? I ask because if it is a recent DVD, Shrink alone may not be up to the task of removing all protections....
i believe the program is on when u see the Red fox head in the lower right hand corner on ur PC(in the system tray), u can right-Click on the fox head and see if it is ENABLED, if it is u should be able to open shrink and continue with the shrink program
edit-
More clearly AnyDVD runs in the background while u use DVD Shrink, just make sure it is enabled and ur good to go.
it doesn't work!!
i have installed AnyDVD... i reinstalled Shrink...
but with no result... it's giveing me the same stupid error...
AnyDVD is on... the "Enable AnyDVD" is checked...
and when i am with the mouse over the red fox in my bar, a pop-up message is displayed: "On:1, Off:0, Empty:0"
maybe i don't know well to set it up... can you help me? again?
