[FIXED] Sims 4 - "Double-check your connection" or "Game License is Invalid"

I am unable to get into my Sims 4 game. I have updated the EA app, uninstalled and reinstalled everything, and I am still getting an error message. The message keeps saying that my game license is invalid. It tells me that EA can't read the license file, and suggests clearing my cache. I have tried to clear my cache! I have done everything I can, and it still won't work! Can someone please help me to get my game to work again?

Thank you.

Im on the EA app and I'm unable to launch the sims. 

Ive restarted my pc, I've repaired the game, I've removed my mods folder and all I'm met with is:

I've heard of this error before during the origin to the EA switch, but I've been on the EA app for a while now....

I'm worried i wont have access to all the game titles I bought now...

Hi, I'm not sure how to get to the master thread about this.. But I had the Sims 4 launch problem for MONTHS through EA.. I tried every suggestion under the sun. Nothing worked. I've had a variety of error messages and on my last thread, we narrowed it down to be an EA problem.

Yesterday, my friend made a suggestion that finally worked. I didn't have Sims 4 on Steam before.. I uninstalled Sims 4 from EA and installed Sims 4 on Steam. I then connected my Steam account with my EA account and launched Sims 4 through Steam.

I am FINALLY able to play again. I'm sure this won't work for everyone.. But it might help a couple people.

I have this issue on PC.

I kept getting a message saying EA couldn't find a connection despite having a clear internet connection for two or three months.

Now I'm getting a message saying that EA can't read my sims 4 licence.

I've repaired the games, uninstalled and reinstalled the game, cleared my cache multiple times, and restarted the app.

I have every pack and kit except for the Home Chef Hustle Stuff Pack, the Modern Luxe Kit and the Poolside Splash Kit.

How do I fix this and why is this happening?

That link just brings me to another threat that is about a connection issue. 

Hey everyone,

We need your help with the investigation into the "Game License is Invalid" error in the EA app for The Sims 4.

Please provide us with the requested information mentioned here.

Thanks a lot!

I have had this problem since July. It is the same pop up. I downloaded the horse ranch pack and this started. I've tried everything. It is really upsetting. 

I have tried everything to fix this issue but nothing works. My game has been broken for months. Nothing I do will fix this issue  I have tried uninstalling the game, the ea app. I've tried restarting the game, I've tried deleting the cache like it says.

I brought this game when it first game out. Its now gone to * becuase it's free. Unfair. 

So this is a fun new issue I discovered last night, whatever I do I cannot launch my game. If I try to launch it online from the EA app, it says my game license is invalid (screenshot attached) and if i try to launch it offline, it says my license has expired and gives me the error code EC:204. I looked around and it seems like this particular issue was "solved" a few months back on a different version of the EA app.

I have tried everything I've been told to do by popups and all I can come up with. I've repaired my game, uninstalled it, cleared my cache. Everything. I do not use any mods. 

I bought 2 news packs last night right before discovering this- and I'm sure y'all will understand why it's quite upsetting to not be able to launch a game whatsoever. Hoping someone can help!
