Broken store after failed attempt to upgrade

I didn't do enough research before attempting to upgrade from 1.5.6.4 to 2.2.0.0 and couldn't get past the Upgrade screen. So I re-uploaded my backup of my 1.5.6.4 store, but now I am getting errors on the storefront and am unable to log into admin. The store is http://www.mega2016.org.uk
These are the errors on the store front -

You should better have invested your night on reading about this before, on this Forum, and/or at least saved your existing DB, before starting to play around. But just try to find out, if your Hoster has an older Backup of your DB, because your attempt to update/upgrade obviuosly already 'harmed' your existing DB, so making it unusable for the re-used old Version.
Good Luck !

I have the sql file backup that I made through the shop admin, but I can't access admin now to restore it? Can I use this file to restore my database through phpMyAdmin4? Or am I better off trying to get the host to roll it back?
