My PvZ game acts like I did not buy it

So today I decided to play PvZ game after a whole three years (medschool.) and it said (see the screens) we could not activate this game on your computer on your origin account, provide the key code or buy it / register in the account it was boight from. Dude it was bought from this account back when EA was Origin, but so were the Sims 4 and it is fine. So then I tried to enter the key code, but the game said my computer was offline which is bull**bleep** of course. I really do not want to buy it again... Does anyone have any idea what to do ?
