Hello ! 
I have a problem and maybe you can help me
So, many years ago (2013) i used multibit on my mac. I just opened multibit, create an adress and used it to transfert bitcoin. I never used a password. During 2 years i send bitcoins 1 time per month. One day (2015) i sended bitcoin on my multibit adress before open multibit. When i opened it, SURPRISE ! the bitcoin adress had change ! and there is no bitcoin money. When i checked the public key i see the transfert and bitcoin money.
When i try to recover wallet or key in multibit file, nothing ! so after read some articles, i exported private key ... (too late).
Now we 're in 2021, i find my multibit wallet from 2015 with the new adress. I try software to recover old multibit file from when i created the wallet but not files .wallet or .key ...
I have a chance to backup my old wallet ?
Thanks
