Missing base game graphics

[Yolu]

I loaded up my game some time ago and found this:





And my game crashes anytime I try to move sims into a maxis lot.

With a bit of searching I've:
1. Discovered that the most likely cause is  a corrupt object file
2. Replaced the file (as well as the other object0.. files) from the compressed zip of my original cd - no luck.
3. Carried out a complete uninstall/reinstall - this seemed to solve the problem until I put my saved games and downloads back in.
4. Did another uninstall/reinstall without putting the saved games and downloads in as well as marking both TSdata/Res/Objects and Sims3D folders read-only.

The same problem persists and I really have no clue what to do next at this point. Any help would be greatly appreciated.

I had that problem about a year ago, but it was the trees and clouds in the neighborhood screen that looks like that. Turned out it was a corrupted cd, I borrowed my friends' base game and it works just fine. Didn't know that you can get a replacement disk, I ended up buying the base game again

Thanks for replying I managed to get my hands on another copy and reinstalled but with the same outcome. It's really quite baffling

Got anything in your downloads that override these textures?

Nope. This is a brand spanking new clean untainted install. There isn't even a downloads folder.
