Somewhat belated response to this, but I was focused on Black Diamond GC and we were dealing with it internally.
If you have Windows 10 and using Edge for WGT, the problem is not the Flash update or WGT.
It is the Microsoft/Windows "security" update to the Flash update. Plenty of computers guys better than me, but MS hates Adobe.
One can kill the updates with Windows 10 by going to Settings, updates and uninstall. But then there is 2nd step. One has to download Windows 10 "Search and Hide" tool ...that is searchable but get it from MS … then hide the damn thing.
That is to prevent MS from trying to re update it every day.
There are multiple updates for some of us since 6/7, so kill them all if you see "Security" in title.
Alternative, as noted above, is go back to Maxthon. The best techie in my club has another alternative, but I never heard of it so not prepared to mention it in public.
