Glad to hear from you, Natalia!
Technically, all support you have received already to get it up and running doesn't come standard with our free license
and then you can see the full comparison table here: https://www.webrotate360.com/pricing.aspx
(let us know if anything needs clarification).
There should be a table in your database called wr360product (possibly with some standard OpenCart table prefix in the front of the name). It stores the list of configured 360 products views. And then we use the standard OpenCart settings table to store module settings. I can't remember the name of the table but if you need I can find out. PS: there're no external databases for storing the module config...
