@holo-alan Where did you get this sentence?
Please keep in mind, a free plugin is made in the authors spare time. To expect he or she has also to give support is not fair. The community, which is getting the work for free, is responsible to help each other.
If the plugin is not working for you and you are not able to get it up and running, you can choose another one.
Nevertheless the author is answering posts so many times here, so you can not say he is not supporting the plugin.
If you need more support than you get here, you should invest some money, buy the PRO version and get the PRO support directly.
Think about this! Full stop!
