Although, I see some weirdness with the city and school etc on your screenshot, so I do wonder if there's a problem with OOTP not being able to write to your hard drive in some places where it needs to?

You might want to try reinstalling on another drive, or on the same drive in a different location. Possibly move the saves folder as well, because you might be lacking the proper permissions in your current save location.

You should also probably make sure to whitelist OOTP in any anti-virus or anti-malware programs you're running to make sure these are not somehow corrupting your data.
