I'm using Win XP Pro, Nero Express 6. Just recently I was able to read and write with the burner I have Lite-On Combo SOHC-5236V. Now I can't burn. It keeps giving me an error message "Burn Process Failed". But it reads with no problem. Even installs programs from it. Why won't it burn? I tried all different types of files to burn and I still get the same error message. I even updated the firmware. Still nothing burns.
