Hi,

I was discovering the game with my recent account and i found the treasure code site, i got all the items for my first pet... when i got some respect Points, i bought a brand new pet e tried to do the codes again, but it donsent work... it's really sad.... I'm a noob and i dosent know this... now i cant create other account, because is an Ipod Acc.... What can i do?

Some itens are really good and i cant play without them....

Thanks for the attention...
