Did not autoupgrade WD my cloud 4TB to smartware pro

Just bought Wd my cloud and supposingly it should auto upgrade smartware to smartware pro automatically as stated in the manual. However nothing happen and I did not receive any activation code either. What should i do?? Please help…

been a long time but as I recall there is not upgrade code. Install smartware on the PC, connect it to the mycloud then there should be an upgrade option somewhere
