A couple of weeks ago I added some new pictures into the Paintings folder for sims to do at the easel, I have had custom work there forever. I also copied some MP3s into the music folders to some of the radio stations. All of a sudden the sims at the easel pull up a blank window when doing a custom painting, plus the only songs that will play on any settings is the maxis stuff. The neighborhood photo in the SC4 files are just a blank grid., I completely uninstalled my games, cleaned the registry and reinstalled with no downloads or anything. Starting it for the first time to check it I find the SC4 map is still blank!! Has some media program stolen the file extensions or something? Why is a fresh install still corrupt?
I have all game expansions and celebrations installed on a win 7 home built computer.

I know of one of those issues. The hood image is blank because it has no image the hood should be there but you haven't set a picture to the main menu screen. I don't know how to but there is a tutorial to put a picture file so it shows up there.

Other than that I don't know about the other problems.

They were there, now their gone. Its a blank icon.

Re-installing only helps if the problem is with the game installation files, which it almost never is.

This sounds to me like an argument between programs on your computer. Something - an anti-virus? - has either destroyed those pictures, moved them, or in some other way made them inaccessible. I know new anti-virus software sometimes wrecks game files that it doesn't recognize, but wouldn't expect that to be the problem for .mp3, .jpg, or .png files. I would start by looking at the files themselves, though honestly I wouldn't know what to look for.

That could well be it. I installed Panda Internet Security before the issues started. The game runs fine for now, I will live without them until I wipe and reload my older WinXP computer and will reload on there. Its not running Panda. Thank you.
