When upgrading, the files in the install directory folder overwrites the files in user common folder, so move or remove your files in install directory to another folder and and your files in user common directory will never be overwrites/replaced.
To get your files back, use your System Restore (Start > All Programs > Accessories > System Tools > System Restore) and restore back to the day before your MT5 being upgraded.
