We have finalized the DRM-free version of Zoom Player Steam Edition, it will be synched later today.
The changes required to remove the DRM mean that you will have to re-install Zoom Player Steam Edition from Steam.
For users who previously installed the DRM version, a new dialog will pop-up stating that you must re-install from steam. You will then be given 10 minutes to export your current settings through the options dialog to ensure that re-installing doesn't wipe your current configuration.
Fore information on exporting and importing your settings, read the full post:
