Direct link to setup executable: http://www.ftdichip.com/Drivers/CDM/CDM20814_Setup.exe
I've never been able to figure out what the problem is. I continue to use a different computer (running Windows 7 x64) and it works with the FTDI driver. I have no idea why it doesn't. I have no updates. I haven't tried any of the suggestions posted here (yet). I will update if/when I do.Thanks for the support!
