CHIRP application fails to download from radio after installing update

Hello,
I installed the latest daily update of CHIRP (chirp-daily-20120720-installer). When I start CHIRP, it boots up fine. I clicked on radio after attaching an Alinco DR-235 and using an Icom OPC-478 (RS-232 to radio cable). When the download from Radio begins, I get a short flash of the ‘cloning’ popup, and then an error window is shown before the daily update. I tried this with the CBTI Alico mobile software with the same cables and settings and it worked fine. What could have caused the error after the installation? Please advice. Your help will be greatly appreciated.
