On kazaa i downloaded a movie, and when i tried to play it it told me to click here to acquire a license. without thinking i did...doh. so i dont know what this means. but the next movie i played in windows media player it said that i had acquired a new license and should back it up to insure it doesnt get damaged or anything. so what have i done, and what can i do to go back to before. and i have turned system restore off several months ago.
