Hello @Michele - Thanks for reaching out to us.
Our Product team have confirmed that there is some ongoing issue with OVA and they are releasing new OVA today which should resolve your issue.
I see that you are also facing issue with MySql. Did you refresh the browser and try installing it again?
If that doesn't work, we are releasing the new patch of OVA tonight. You can try downloading OVA again tomorrow.
Sorry for the inconvenience caused.
