[chirp_users] Can't Program UV-5R+

Afternoon, I have 2 UR-5V's refuse to download the factory set up prior to me uploading my programing. For the first radio the error code is; Radio refused to send block 0x0000

For the second radio the error code is; Radio refused to send block 0x1ec0

Using windows 7 Never had trouble with re=-programing BF UV-5R's before this Any suggestions Thanks, Jay
