So irecently had an issue where the error mp4box.exe has stopped working at the end of a conversion using Ripbot. I went back and did a system restore to an earlier date and that seemed to work. Just last night it happened again. I am curious if anyone has had these problems and if so how did they resolve it? I just recently installed cyberlink media suite 8 and have a feeling this might be an issue but am very unsure since I have had some conversions work and some not. Any help is greatly appreciated.
