In order to solve the issue, I suggest you remove the software from your computer (Control Panel > Uninstall a program), run CCleaner to make sure that there are no leftover registry keys in your system and install the application again. Also, configure your security program and Windows firewall to allow the application to connect. If it still doesn't work, use the contact form from the official web page or connect@dionglobal.com
