Well I’m completely stumped, I got a 400 and installed the ADMS-7 programming software on my laptop. First I attempted to use the cable provided with the radio to clone the data and I get “format error”. Then I went out and bought an sd card and tried that. I copied the radio data to it and then put it in the computer and the file is showing but when I try to load it I get “error” immediately. There is no other information except “error”. I’ve downloaded all the drivers and updated the software. I read all the manuals I have copied the CLNTFTM400D dat file to the laptops hard drive, and tried everything else I can think of including a different sd card, and I’m completely at a loss here. I’ve uninstalled and reinstalled the software several times as well. I can open the dat file with notepad and there is data but I don’t know computer code so I’m not sure what I’m looking at. I’ll post that code if anyone thinks it will help. Seriously “error” how the hell do they expect you to diagnose the issue if that’s all the information you get?
