Hi, sorry for that. We will do our best to provide you with a student license ASAP.
In the future, in case of similar issues, please contact us through our official support channel - https://corona-renderer.com/link/contact-support
Yes, please always use that link to contact us about any serious issues such as:
licensing
payments
serious bugs
Writing on the forum is fine too, but it is a more “unofficial” channel so we can’t guarantee that some important topic will not be overlooked (we do our best to avoid that of course!).
