Before you started the process, did you initially create a CHIRP template by doing a Download from Radio.
CHIRP supports over 80 various models and requires a template to identify the type radio it will be programming.
Refer to (1.1) http://www.miklor.com/COM/UV_CHIRP.php
I hope this assists.

Just a thought as my UV-5RC wouldn't up load from my laptop unless after I'd finished entering the frequencies etc. into Chirp I had to save the page and then X out that file on the screen (plain Chirp screen left on display) then click file, open and then click on the frequency file I'd saved then open, at this point all that I'd saved previously was back on the screen and then carry on the usual way to upload to the radio.
Works on all my different rigs.
