Finished downloading Sims 4, and game is no longer opening :(

I recently got a new laptop and have finally got around to downloading the Sims 4. I decided to download all the DLCs/updates over the weekend, and at first I opened the game after each new DLC (to make sure it was working), but after awhile I stopped doing this. And that was clearly a mistake, because now when I try to open the Sims 4, it opens for a second or 2 (just as a plain white screen) and then immediately closes.

I'm not sure if I accidentally forgot to install one of the DLCs, or if I messed something else up along the way, but could someone please help me fix this??

(I've downloaded up to the Seasons update 1.46.18.1020) (At least, I'm pretty sure I have)


Also, I did the Sims 4 validator thing, and this was my results:

report:

You are missing the 9 files ClientFullBuild.package.


I can upload these for you, but that's approx 7.5 GB in size
see HERE
Download jurassic.rar, extract with Winrar and copy the 9 files to your install folder Th Sims 4\Data\Client.

Alternatively you can install the base game again and move those files to your current installation. Just make sure your game is not in "C:\Program Files (x86)\Electronic Arts\The Sims 4" because that's where the base game installs to.
