updating the baseline??need help

Hey,
I have a live project in which some activities have been added and resources assignments have been updated.but the project start and end dates are not matching and the budgeted cost has also changed.i need to get the baseline the same budgeted cost as the live project.

Initially i removed the actuals from the live project and tried to get the start and end dates to match.but i have not met with much success.

Any kind of help would be appreciated!!!!
