Im trying SDP onprem in Enterprise mode with Endpoint central integration. Ive reverted to free licence because it represent the feature set we want to license in the future.
Lots of sites were created automatically when importing users via Active Directory. Ive been able to remove all users from SDP to start fresh with the "real" import but all sites remains. When trying to delete a site, this error message shows up: Error in updating site association. Retrying, i can see this message:

But theres is no Assets module anymore - since we converted our Enterprise demo with a registered Free license.
How can i delete those site now? Can we do a manual/DB edit?
Also tried to get back into Enterprise trial mode but i get a message saying that the email adress provided is not registered in ME database (which i know is not true since ive registered my Free license)
Anypointer will be appreciated
