Please bare with me for I am computer ignorant and don't understand most of the computer jargon that is used here. I have the ACC program installed and I have a file set up with all_channel.dat, antenna_list.dat, DVBS.dat. I do not understand how to open the file to make sat/channel updates. I select the file, hit open and nothing happens. I do understand how to send the data from the PC to the AZ Box Premium Plus and have accomplished that.
