chainfire, the developer, has stopped sharing the app due to legal issues. he may be working on stronger security but right now i think all you can do is the lowest (64 bit). you dont really need to use security anyway since this connections bandwidth is not large enough for sniffers to log on to it.. but to each his own..

as to the user who says this is bug ware, i ask what version are you using? im using v.81 (its up to v.91 now) and its rock solid on the mogul... if you are using security i would suggest you keep security off until you get good results and confirm it works then use security...
