suggestion: make purchasing your product easier

What is the deal with the bullshit I have to go through to give you my money? I hate to bust your bubble, but most people only have free email. You won't accept paypal just because I have a gmail account? what the hell man? I hope that is not indicitave of the customer service side of your company.

as far as i know this restriction is only for forum registration. i got my license with a free-mail paypal account.

Well, as you see, not anyone is accepted by Internet stores.

When you attempt to purchase something online, most stores check your personal data, address, email, credit card and your payment history. In your case, probably something raised a red flag. You can contact the store and ask why they don't want you as a customer. It could be just some misinformation. But I'm afraid we can't help with payment problems - we don't make those rules.
