JVZoo support can only assist with anything related to the JVZoo website and can only provide support for the JVZoo website.
JVZoo cannot provide support for individual products because they are owned privately by the individual seller and JVZoo does not have login details or other product specific information.
To get support for a product you purchased contact the product owner directly. The support contact information is always on your JVZoo receipt above the download link.
You can also login to the receipt area to locate contact information for any product: http://www.jvzoo.com/portal
