Cant link account, progress wont save

Hi. i never had warcraft 3 and i played it mainly at friends house, recently i bought reforged and it seems i have to link some account to it, i have my blizzard account, but thats that.

another problem im facing is that although i ran the game as administrator like you suggested, the progress, nor the resolution options i choose is saved, even between campaign missions, the skill’s and items i had are removed and i start with some defualt stats on my hero
