I believe if you received an email with link for the Beta version (19th March) , an email for the official v9.0 release should have followed (26th March).
unless your license expired between those dates ..
(unsure how it goes)
As suggested above it would be better to contact
[email protected]
You can just install the new version over the old version location(no need to uninstall) or install to a separate location.
ps .. if you wanted to install the Beta version immediately ... I would Install to a separate location temporarily while you await response from Support.
