Easel and grbl 1.1

I had a forced lay off of a few months so when I came back to my machine I decide a new broom was required so I bought a new Arduino Uno, installed the latest Arduino software and Easel driver. I loaded grbl 1.1, did a few adjustments to suit my home build machine only to find that Easel refuses to see my machine. Previously my com port was always com 3 but now it is com 5. UGS and Gcode Sender both see the new com port but not Easel. I realise I did too many changes at once but any help would be appreciated
