[chirp_users] Baofeng UV-82HP, cannot download from radio

Hi, I have a brand new UV-82HP. I connected it with the cable, and the cable loaded the USB Serial driver automatically. When I plug the radio in, the computer sees it on COM4. This is on Windows 8.1. I'm running the latest version of CHIRP, 20150814. The radio's firmware is US2S35. Anyway, when I try to download from the radio, I get this message: "Radio refused to send block 0x1ec0". The display on the radio seems to reset when I do this. I'm not sure what to try next.The cable is plugged in securely. Any ideas what to do? Thanks!
