I have used Power 2 go express to make music compilations for about six months but now when I try to burn a CD the program freezes and stalls my PC. I have to restart the machine in order to do anything else. I tried burning with Window Media Player and that was fine. I know I could use this but I find the power2go much more user friendly. I recently installed some Anti-Virus software and Zone Alarm so I'm not sure if this has affected it. Its a Sony DW18 Burner.
