Is this company out of business? I'm desperately trying to reach them for a license number that I paid for through PayPal.
No, the company is not out of business. Their website is working just fine. To get in touch with the developers, use the Contact Us page provided on the left menu.

You can call them between Monday to Friday between 8.30am and 4.30pm (NZ time) at the following number: +64 21 771 636.
I have been leaving messages to that email and phone voice mail for a month now with no response. Many parts of the website produce errors too.
