All vector assets that are not Premium, are offered under a standard and an extended licence. You need to buy the correct licence for your application. I do not see a promise of editable text, even that I would probably also assume the text to be editable. 

I suggest, you contact Adobe customer care for this. Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled, you need to accept cookies! If the chat window fails to open, or is non-responsive, use a different device and/or browser to start the interaction.
Support phone numbers may be found here: https://helpx.adobe.com/contact/phone.html. Kindly note that phone charges may apply.

Important: Adobe does NOT contact you unsolicited by e-mail or direct message. If you get contacted by direct message from a person, claiming to be an Adobe employee, look at that profile and look, if they bear the “Adobe Employee” marking under their name. Adobe support does not use Skype to give you support.


If in doubt, ask the forum.

*Clarification: should have said I liked the design concept - I didn't want to use the design as is, it wouldn't have been recognisable after my edits.
