What Chrome version are you using?
Is it 32 bit or 64 bit Windows OS?
We were having an issue with build 66 (17.0.963.66), but the latest Chrome build (17.0.963.78) seems to work (Windows 7 Enterprise 64-bit with Chrome 32-bit). Can you verify?
I have 17.0.963.66 32 bit. I'm updating now to see if that fixes it...and
it did! I'm up and running. Thanks! Thought I was going crazy!
