How to roll back from MegaEPG

I installed MegaEPG on Vista MC. it works well but some of the info is either missing or in error.
I tried to roll back to the regular Vista-Yes EPG. During the set up it still tells me
that MegaEPG is the only one available. What is the correct
proceedure to roll back from MegaEPG? I would like to avoid if possible uninstalling MegaEPG so i would be able to switch back and forth in case of issues.

thanks, Avr

You can safely uninstall

You can safely uninstall MegaEPG since it keeps the megaepg.ini configuration file and will use it on the next install. Uninstall is the only way to return back to the Vista native EPG.
