In order to find the reason why the program doesn't connect, you should head to the official website of the product and try to log in to the customer area using your details. If you can do this, then the program can't connect due to a problem on your computer or due to an error on the registration server. If this is the case, you should check if the application isn't blocked by Windows Firewall or a third party utility firewall like an antivirus.
If you can't access your account, try contacting the developer on the official website under the Contact section. They can provide more information about your problem.
