Hi, I have the same problem and can't get past "error connecting / make sure the agent is running" message.
system: win7 64 bit
windows firewall off
all antivirus that could be blocking it off
agent is running in the tray
board shows up as "USB Serial Port (COM19)"
tried to start up the agent as administrator and/or compatibility mode
tried opening from waveformslive.com or http://localhost:42135 directly (it will open, so the agent is apparently running)
tried Chrome and Firefox, no difference
I'm attaching dxdiag report if it helps. Also, some screenshots: https://www.dropbox.com/sh/1i8r1v2logeej10/AAD5DUfo-bpsNjnMT81Dsq8La?dl=0
You can see the XHR request to http://localhost:42135/config gets "cancelled" after 5s timeout.
Would you please advise how to resolve or further debug this.
Regards,
Mario
