I have audio cleaning lab and just move up to xp. The thing is now it does`nt work .It asks if the cd is a real one and trys to registered it and it can`t. The thing is that when my p.c was on Me it played find. Second question and maybe i should`nt ask this but. I`ve downloaded a demo verison and plays fine but the only audio length is 3.00 minutes long.Does any one know how to make it longer.
