From what I see on the official website, the application is still in development. However, its license is commercial, which means you will have to take advantage of the support section.
Use the following email to get in touch with the developers: support-inpixio@softcity.com
However, if the product doesn't work anymore, you can re-install it if you have the installation package. In case you're lacking the package, the technicians will provide a new link to download it on your computer.
