Looks like Mach 4 is not a fan of Creator Update... I got the "official" update via Windows Insider program last night.. Now when I open Mach 4 I get the following error (which doesn't look like an error but popup box with big red & white X suggests something isn't happy..

I thought it was due to some Lua scripts I was working on, so I uninstalled/reinstalled mach.. same errors with a fresh install.

yah.. no plugins are loading... something isn't happy anymore

Two uninstall/reinstalls and two reboots later its working .... ¯\_(ツ)_/¯ ...
