Addit! Pro for FSX,,,,, Are They Still in Business?

I've bought the program last week. They got my money.
However, I did not receive the 'unblocking code', which makes Addit! Pro.... Useless.
My e-mails came back as "undeliverable".
In addition, since the 19th of August, their site is DOWN.

Are they still in business? Is there any news about them?
