Hi there, I'm having problems recovering my save files from my old laptop which crashed with a corrupted hard drive.

Unfortunately I didn't back up any save files prior to this (stupid, I know) but I was able to find someone who could recover them from my old laptop onto another hard drive. However when I tried to copy the files over onto my new laptop I started having issues.

I started a new save with a sim called Shibata and it seemed to work fine so I think it's a problem with the files rather than the game itself.

I've included screenshots to show the problems I'm having, I am unable to see any of the sims or the lots I created in my library (the rest of the gallery is working fine, it's only the things I've made) and when I try to open one of my old save files, nearly every lot has orange/red triangles above them and when you try to visit them the lot is empty. I've tried contacting EA help but they've just sent me links to help pages I've already looked at and tried and I'm not sure what else to do. I've tried repairing the game through origin and reinstalling the sims 4 also.
