I'm currently using SP Page Builder Pro Version: 3.8.7 in Jommla 4.1.5. Since upgrading from Free to Pro i get the following Message in the Backend:

SP Page Builder database update required

SP Page Builder has been updated. To keep things running smoothly, we need to update your database. We strongly recommend you to take a backup in case anything goes wrong.

And there is a Button "Update SP Page Builder Database". If i click on that button, i can see this:

Missing Tables
Table #__sppagebuilder does not exist.
Table #__sppagebuilder_integrations does not exist.
Table #__spmedia does not exist.
Table #__sppagebuilder_languages does not exist.
Table #__sppagebuilder_sections does not exist.
Table #__sppagebuilder_addons does not exist.

And there is also a Button "Update SP Page Builder Database". If i click on it the message changes to the following

Fixed Missing Tables
Created #__sppagebuilder table successfully!
Created #__sppagebuilder_integrations table successfully!
Created #__spmedia table successfully!
Created #__sppagebuilder_languages table successfully!
Created #__sppagebuilder_sections table successfully!
Created #__sppagebuilder_addons table successfully!

BUT: nothing has really happend! If i go back to the "Pages" Site the same message appeares again ("SP Page Builder database update required").

How i get this problem fixed?

Thanks in advance.
