Can't continue Campaign

The continue button does not work and cannot advance to the next mission after victory nor does chosing the next map from the mission list.
Ive downloaded the most recent patch.
I AM playing offline.
I’ve reloaded client, restarted my game etc
Changed graphic settings, reset to defaults too.
I’ve erased and restarted the campaign and now I can’t advance to the 2nd mission at all!! Before it stopped at the “Frostmourne” mission.
