Site down as explained below after update from 5.0.44 to 5.1.4

I attempted to update easyblog on a site that's not supported. The launcher would not work as the site was not registered. It froze and I could not exit out to do a full update. I closed down and then updated with the package and now the site won't load.
Can you advise?
Are there any reported problems with compatibility with community builder with the latest update? This is where the problem came up after launcher failure and full package update.
