The IR remote receiver is being recognized as a keyboard now. You need to remove it from your system's list of keyboards. Open device manager and expand the keyboards section, find the IR receiver-keyboard interface (mine had eHome, which is the name of the driver software Windows uses for my particular receiver), select it and uninstall it. This shouldn't uninstall the receiver drivers entirely, just the keyboard component.
Re-enable all the commands you disabled in Event Ghost, and you should be golden.
