audio4fun extremely hard to download, get serial no. Then when loaded destroys sound card settings on your computer. audio4fun.com, Internet
Tried AV Voice Changer Software 7.0. Password was no good. Bought their cheapest version 14.98 (@1/2 price). Had to join a completely separate network make4fun before i could even try to register. Finally got that solved. Loaded program on computer, my sound card would no longer work. Used system restore to fix problem, why program was even left I don't know. But tried to run again with same results. Sound card no longer worked. Again used system restore to a previous point. All workes well. Destroyed AV Voice Changer software!
