Hmm... I don't know in that case what might be wrong except I don't think you can download 10 mb files through the browser. It seems like you should be able to drag and drop on your PC to the media card via USB with Windows Explorer or using Desktop Manager.
Which method are you using to move songs from PC to media card? If you are using Desktop Manager sync, you might try the other way and vice versa.
