Replacing dvd2xbox new version

[bigmac_4000]

With all the problems copying The suffering I decided to first update my old version of dvd2xbox v4.9 to 5.5. Found file, unzipped and copied whole directory that was created from the zip, of course backed up original dvd2xbox folder just incase. When I choose to run the program on the xbox it looks like it starts to then returns to main menu, Am I supposed to keep any of the files from the original dvd2xbox dir. or did I forget a step. The file came with no instructions, I copied to whole directory file for file, about 8 or 10 meg I think. Thanks
