Discarding Elasticube Changes Pending

Hi, having updated an elasticube model some of the relationships broke and I want to revert the changes back to the last built version; is there a way to do this easily? 

I can't go into the front end view of the model now, so only have access to the list view under the 'data' tab which means I'm unable to manually fix all the connections either... 

Any help is greatly appreciated!
