If you want things exactly as they used to be...
... the best bet would be to uninstall, reboot and reinstall the Olympus Master software.
I do use my Olympus software occasionally, mainly for index printing, but normally cancel as soon as it starts to run.
I prefer to find the camera with My Computer then copy and paste to a chosen folder.
It is really a matter of choice depending on how comfortable you are with alternative software and methods.
