How to update Amazomatic. because asks me every time API Credentails

I have Bought the bundle of all item, and I saw the videos related to Amazomatic and I need to work with it, so I noticed that the version I have is 1.8 and on the contrary 2.1 Version is The video "https://www.youtube.com/watch?v=IEefZLufVPA" where you explain the update for who doesn't have API Credentails. So, the plugin can import affiliate products from Amazon without the need of PA API keys. Please to get back to me ASAP. Thanks
