Problems with Sims 3 pets

[Lydia_96]

I got the sims 3 pets for christmas, I was over the moon and installed it straight away, however once i was in the game many things happened; one of my sims lost all her hair when i zoomed in on her and on her picture, the other sim's hair turned pink, my horse kept getting a line through it's head and to top it off the game keeps crashing. It freezes then goes to a black screen, this happens about twice then i have to close the game via task manager. I have tried the DEP thing but nothing seems to work.I have uninstalled it and reinstalled it, checked the memory on my computer -there is plenty of space- checked my graphics card- also fine- and deleted all of my installed content. I hoped this would fix it but when i went to play it again it crashed. Again. My game is up to date on patched and i have the up to date origins. Is there a patch coming out to help me? If not please tell me what i can do, i just want to play my game, Thanks
