I'm helping a friend install the Palm Companion on a Tungsten E running OS 5.2.1. We follow the installation instructions including responding Yes to the question about having OS 5. The app is transferred to the Palm device when we hotsync. When we tap on the Logbook Pro icon on the Palm we receive the message: Application error lbk_pro-install is intended for Palm OS4.X and below. Please contact the author for a compatible version. Any suggestions Neal?
