LSU Tiger

I don't have any brown boxes, but things that should be there aren't. For instance every park and plaza I plop are just the base color and nothing else. The same is true for plazas that are apart of other lots, such as the civiv center. I just started my city, so I'm just going to bulldoze all the lots, remove all the plugins(because I got carried away... before I read the advice on here) and start over.

Upon loading my city a screen came up saying I was missing two plug-ins and that some textures and props may not appear. The two codes are 812767622 and 1383259789. If codes don't mean anything them I'll post again with pictures of what's missing. Thanks for any knowledge you can give me on this topic.
