yes, your detailed steps did it .... FW1.4 loaded correctly now, thanks.
I just tested the amp with the new firmware a few minutes ago (at my 30W level) on 17meters and had a nice chat with a guy in Virginia... got a 57 report
@ Dave - I remember having the same fault as yours in the beginning and ignored it. With the MCP2200 driver installed (as in the instructions) the computer recognized the MCP chip as COM9 and showed up in the device manager with the correct driver associated.
I now just need to understand my low output level on the upper bands.... as I just cycled through the bands again and get about the same low power out between 17 and 10meters (20meters is fine at about 50W).
