Are you trying to load the profile from Application Data\EAC\Profiles or from the Profiles folder in the installation directory (typically C:\Program Files\Exact Audio Copy)? Try the former if you haven't yet. EDIT: Nevermind, I've only now noticed that you had to reinstall XP, that certainly wiped out all user settings from the Application Data folder.
V1.0 beta 3 creates cfg with E A C V 1 0 0 0. Looks like that one was created with one of V0.99 builds.
If you need your old profiles, it would be best to install the new version side by side with the old version. Then load a profile with the old version and close the program. Open the new version and save the appropriate options
