I backed up and changed a computer .

Well wait for some multibit expert to come here, as a alternative solution you can make a new wallet  (blockchain.info/electrum) and send coins there (If you have any).

Ps: You didn't mentioned your Multibit version number and OS?
And import that image on imgur.com and post link again.
