I bought the limited edition of The Sims 3 Pets, but I just cannot seem to get the special content... First, I got this message saying that "'null' is not an object"... In my language (Norwegian), 'null' is the same a zero. After trying for a while, I got another message telling me that my serial code is invalid. What the heck?? I bought my game through pre-order, so it has NOT been used by anyone else. What do I do? I'm just SO tired of all this. A recent update just made all my simmies go yellow/green-ish, and my pets generally look awful... and now... this? Can't they do anything right??
