Ok sometimes when i down load a song/picture/video it will download fine.. but when it downloads the icon (showing what kind of file it is) dissapears and then i cant view/listen or even delete the item.....

I can preview it just fine the whole way but once it reaches 100% i cant view/listen or delete it. so i have a bunch of crap files on my computer i cant even delte...

why is it doing this?
