Looks broke due to changes in view/explore.

Hi All,

I made multiple Looks using set of explores. Then I made some changes to the view and explores in project and nothing gave error. Now when I go back to my old looks and try to run or edit them, all I get is the error message saying "Could not find the model or view requested". Did anyone faced such issue? Any idea how to fix the broken looks as now I am not even able to edit them.
