Hi thethreeofusmcnutts and luna2009,
Kindly try updating to the newer version (v3.1.1220) and see if the update helps. There was indeed a bug in the previous version where the Easy Voice Recorder (and sometimes the Picture Editor too) get removed when LR is installed as an update (from any v3.0 version).
If the update doesn't help, please try uninstalling LR completely (choose to "remove additional data") and then reinstall the latest version. In case you have customized lessons that you'd like to save, make sure you backup your library before uninstalling LR.
