Oh no!!! You'll find that site listed here Known Scam Sites (click on link)

Options:
1. get your $$$ BACK!!! (music members)

2. I'd recommend you go to your Credit Card company & ask to speak specifically with their fraud/scam dept. & tell them you were scammed over the net & didn't get what you paid for. Normally they will refund you. They offered you LW pro right? But that's not what you got. You certainly didn't get OSX burner program. In any case, they were making promises which were false in the advertising on their website.
