Unable to start - Cannot start because game data is missing or damaged

Good to know this is still an issue and that EA doesn't care enough to help us solve it.

Here is my DXDiag in case anyone is actually willing to help

JMYeager85  Sorry for the late reply.  I've been away from the forums for a while and am still catching up, and not many others ever post in this section.

Anyway, please try the suggestions in the first post of this master thread:

[CURRENT ISSUE] Sims 4 Unable to Start, Game Data Missing or Damaged | EA Forums - 11819181

If none of those help, you can try the other suggestions here:

[CURRENT ISSUE] Sims 4 already running | EA Forums - 11818313

I have gone through every one of those steps, as I mentioned in my original post.

JMYeager85  Try changing the time on your computer to something different, then letting it sync with internet time again.

If that doesn't help, open this location:

C:\Users\your username\AppData\Local

And remove the Electronic Arts, EADesktop, and Origin folders, if they exist.  Revo may not delete all of these during the uninstall process.

Any game that places files in any of these folders should be able to regenerate them when necessary, but just in case that doesn't happen (as it very occasionally does not), it would be best to move the folders elsewhere rather than deleting them outright.
