I don't know what is the problem. It is showing error 404. When I'm trying again to register the program, it says "It is already registered". What can I do?
In order to solve the issue, navigate to the official web page and fill up the registration form using a different username and email address. Also, download the latest version of the program and during the installation process temporarily disable your security program.
