I have Windows ME. I first got this error message using DVD Shrink 3.1.4, i thought it may have been a fault in my download so i unistalled it and tried to download the new version 3.1.5 which wouldnt download for some reason??, so i installed an older version DVD Shrink 3.1 off a disc that my friend has and i still get this error message. This is the first time i have tried to use DVD Shrink, its is not like it has just stopped working in the last few days because i may have changed something. Thank you.
