Fresh Joomla3 and a fresh Komento and Error 1064

I'm not an Joomla programmer, but will establish a new platform by myself.

Joomla Version: Joomla! 3.5.1
MySQL Database version: MySQLi 5.6.19-67.0
Komento Version: latest version from your website

API-Key installed: no (because I don't know where)

I have installed the free version because of the test if this can handle my requirements in specially the collaboration with the SP Pagebuilder.

After my installation I was not able to test anything because the ordinary Joomla Pages went down with an database error: 1064. Something is wrong. I read a lot of information about this issue but found nothing for my special case.

I thought that I need maybe to create an API code but I found no form in which I've be able to put it in there.

Anyway. It would be great to have a look to my problem with the error 1064. Maye you are able to give me an advice how I can link the Komento App to the SP Pagebuilder APP (this is additionally I know but required to buy this software)

Have many thanks for your assistance in advanced.
