HAVING TROUBLE INSTALLING AND PATCHING SUPERNATURAL

I'M HAVING TROUBLE INSTALLING AND PATCHING MY DIGITAL COPY OF THE SIMS 3 SUPER NATURAL.

IVE READ THROUGH A LOT OF THESE PAGES AND SEEM TO BE HAVING THE SAME PROBLEMS AS A LOT OF OTHER PEOPLE, EXCEPT NONE OF THE SOLUTIONS ARE WORKING FOR ME. WHEN I GO TO INSTALL MY GAME VIA ORIGIN IT TELLS ME TO UPDATE MY GAME THROUGH THE LAUNCHER BUT I CAN'T GET MY LAUNCHER TO CONNECT TO ORIGIN. TRIED MANUALLY INSTALLING PATCH 1.38 AND 1.42 BUT WHEN I GO TO INSTALL THEM IT SAY "UPDATE ERROR, INVALID FILE FOUND"

I BOUGHT MY GAME THROUGH GAMESTOP WHO WONT REFUND DIGITIAL DOWNLOADS AND APPARENTLY EA ISNT RESPONCIBLE FOR MY GLITCHES EVEN THOUGH LOTS OF PEOPLE ARE HAVING THEM

PLEASE HELP. IM ON THE PHONE WITH EA CUSTOMER SUPPORT AND HAVE TRIED MANY THINGS BUT NONE OF THEM ARE WORKING!
