I have attempted several times to create a CD of .wav files. The results are frustrating. The software hangs up in different places and then freezes the computer completely. At times, it will seemingly create the CD but when it is played (on computer or other system) it will "hang up", repetitive noises occur and the computer freezes up. My OS is Windows7 and the computer is a Dell Ispiron, relatively new. Files were created on WavePad. Can someone help with some advice on this issue? Has anyone else had the issue and solved it? It is becoming a bit costly attempting to burn one CD after the other which turn out to be unusable. Not happy with this product!
