Appreciate any help... Bought Win 10 pro key w/ office 2019 key, finally got my new build together today, tried to activate, no joy - key not for this version of windows. Logged in to urcdkey, tried to chat, nothing but blank window popped up. Tried disabling all blockers, etc., still blank window. Tried with IE11, couldn't even log in. All of this from my old win 7 machine. Is there any "special sauce" that I need to look out for in all of these new features in Firefox, or some other way to contact urcdkey? Thanks for reading this.
