thanks guys. guess I will just leave it alone. its not worth the trouble just for one address slot.
what you stated shawn was what I was afraid of happening. alan is correct also. the only problem is if I do a factory reset on the remote. then in order to get back the one address. I must add all my engines again one at a time. thats over 50 engines. plus every engines soft keys will have to be rearranged to the way I like them. not worth the trouble for one address IMO.
in the future I will back up my remote more often and keep it current in my pc. my last saved update was about 30 engines ago or around there. I just was not expecting this'll sort of gremlin to ever pop up. oh well. thats dcs for ya. thanks guys for all the info.
