WMP12 not working?

[Grandpappy]

I open Windows Media Player,go to the burn option,insert a CD-R disc into my D drive,select Audio cd and drag my songs across 'till I've got roughly 16/17/ or 18 songs/tunes in the list. I then click on Start burn and sit back and wait. After a while the cd is ejected from the drive which is I assume is ready to play in the car.Oh No! If I check the disc and 'open' it I have 18 tracks of CD Audio Tracks all of 1kb and if I right click and look at the properties it just shows the blue disc with 0bytes used and 0bytes free. What is going on? I've used WMPlayer before and it's worked. I've even un-installed it and re-installed it and seem to be following the correct procedure,but I now have 3 discs headed for the bin!!
Can anyone help,Please??
