I paid $49.95 for Wondershare for Mac. Company never gave me a registration number. Their online help works very spottily . I told them that the number I got bounced out, but all they did was send me the same number. You go in a circle, even assuming you get somebody to help you in the first place. I'm beginning to think this whole thing is a SCAM. I paid with PayPal, so getting my money back is going to be a hassle. Lousy company.
