Oh, I got a red-warning!!! I hope someone would still help me!
On my challenges attempts I've realized there must be something wrong with my game. I might as well just delete everything like Metro mentioned at the beginning of the thread, specially because if I go to the "saved" file my most recent games aren't there, neither the screenshots. I don't know where everything is going!
I started playing with a special offer I found of the vanilla game + Pets, then I got the Supernatural expansion pack, of those three I have the CD's. Then I purchased Ambitions over the internet, on a "EA Origin" link I found here... so my question is, if I un-install and re-install everything, what happens with the expansion I bought over the internet of which I don't have a CD copy? Would I lose it? At first I thought buying over the internet was more convenient, and I was so ready to go get more expansions... but now I'm not so sure.
