Trying to setup 8000hd. I put a file on thumbdrive and loaded onto receiver, with no trouble. I loaded another file on the thumbdrive and tried to load to receiver, but it now tells me No device connected!. I tried another thumbdrive with the same results. I then loaded the hd5 with the loader thru the pc. All that I get is no service or scrambled and fail to get serial from server. Any help would be appreciated.
