No API field for updates, after new EasyBlog launcher install

Hi, I have installed com_easyblog_launcher_pro_5.0.40_joomla today for the first time, I had no issues with installation, the documentation was excellent and there were no errors or problems.

However, when I open the Easyblog Dashboard, I see on the right hand side in the update area, "Requires Updating" and a note to please enter the valid api key.

In your documentation on this page https://stackideas.com/docs/easyblog/administrators/upgrades/single-click-updater it says to go to Joomla > Components > EasyBlog > Settings > System > API Key however on my System page there is no API Key window for entering this information.

Is there some other instructions for editing API Key?

Running Joomla 3.6.4.

Thanks, Nicola
