Game Will Not Update

I have the same problem my sims is getting worse first it won't let me play now i can not update the resent update it keeps saying the same thing.:womansad:

Frustrating, isn't it :womanfrustrated: ? I've already tried at least six times and I'm getting tired of my Sims glitching everytime they enter a room. I also want the AC units. I have read on other posts though that EA is aware of the situation and we might be able to update tomorrow with no problem (that was after I posted this).

I also cannot update. I am getting the same "invalid file" message.

After researching on simswiki I found that my invalid file is gamedata\shared\deltapackages\p17\code_version which is entirely missing. I cannot figure out how to regain this file though because I do not have my game backed up and I installed it off of Origin.
