I have a major problem with burning Audio CDs, when I first dowloaded Express Burn it was fine I converted several MP3 files to WAV and successfully burned them to CDs. Now they only burn about 2/3 tracks and the disc finalizes and closes. But there are no tracks on the cds but when I try to re use them they will not work? I have windows XP. I am new to this, I now also have a pronblem with my USB out port which I use for headphones and external speakers, this will not work. Anyone who can help with either problem please let me know.

Burns two or three audio tracks then finalizes disc. But there is nothing on disc and pops up 03 73 03 error. Please help, wasting too many blank cdrs
