ES 3.01 Failing to update to latest - stuck initializing database

Hi SI Team

Tried updating using the standard update button in the Joomla back end in the ES component.
Was instructed to go to the SI downloads section where I downloaded the launcher package for beginners.
I then proceed to my Joomla back end and started the upload there.

But got stuck at "initializing database"

I can access the back end but the front end is throwing the following error:

Call to a member function getType() on null

I did an Akeeba back up of the site before attempting to update to ES 3.01

kindly advise
