Events And Exhibitions Ltd incorporated 31 Oct 2008, address is in Grantham, see Companies House.

I suspect more info, directors etc, are probably available if you pay but I don't have an account with them.

Oggie is quite right that the new company will have no obligations in respect of last year's non-event (unless they have arranged differently, and why would they?) but I suspect they may have a barrier of mistrust to overcome all the same. This barrier will be all the higher if it should be the case that the old organisation and the new have directors, other officers, or addresses in common.
