Cannot figure out why Universal GCode Sender won't connect to my Arduino Mega 2560. Any idea what's wrong?? Details in comments

  An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on an Arduino Mega2560

  

I've flashed my Arduino Mega 2560 with grbl-mega, which is supposed to allow grbl to be used with the arduino mega2560. It looks like it flashes OK - I can talk to it with the serial monitor.   But, I'm trying to install it to UGS using the Setup Wizard. No luck! I get the error message every time that it doesn't know how to configure this controller - and that it must be configured manually.   I tried to go into 'firmware settings' to configure it manually, but the option is greyed out under the 'machine' menu. I think it cannot connect to my board at all.   I'm a little bit lost about what to do next. Has anyone been through this, using UGS + Arduino Mega2560?
