I have windows xp media center edition and it came with all the extra windows themes, space, aquarium, etc. Anyway I opened my properties and was gonna change my account and they are gone from the list. My screen saver still works, and my recyle bin is still with the theme, but the rest is gone and I can't get the sound to work on my screensavers. What happened? How do I fix it? I tried that, and it's still not working, I'm so confused, should I restart after? I restarted and they still aren't showing up. I know they are there somewhere, because I still have the screensavers, they are active on my computer, but when I go into change it, it shows up as none. But it's there, it the nature one. and my husband has the fish one on his account and it says none too. SOOO CONFUSED! All I have managed to do was make other things disappear, now my games and calculator are gone...
