I'm trying to contact them for 4 months without any result. Is anything known about the firm? The developer released programs like TextOsterone, SWFnSlide, etc.
On the official website of the developer, there is nothing stated about this matter. Also, there is no information on the Internet that will suggest that the firm is out of business. Until this point there is no information regarding the developer. You can visit the official website and try to contact him through different methods. You can find all the information that you need on the site mentioned above.
