Why can't I paly 2 songs out of 8 downloaded. 6 are fine. 2 I have authorize the computer to play it then iut tell me I am already authorized but only plays the preview version of the songs on those 2 even though it show to have been downloaded and bought

I keep getting this error. Yesterday as I downloaded 8 songs from iTunes store the computer paused then continued. After seeing all the songs were downloaded I tried to play some, 2 kept telling me that I had to authoriae the computer. I reauthorized the computrer only to reveive a message that the computer was authorized. I still can't play the 2 songs other than going through the authorized computer template then when I play those 2 songs I only get the preview version even though it show all songs were paid for and downloaded

I have a windows 8 64bit operating system
