Hi, hoping someone might be able to point me in the right direction.

I'm trying to get funds off multibit classic but it is saying my password is incorrect. What I don't understand is that i'm pretty sure it was not password protected last year when I transferred a small amount in and out. I remember not needing a password at the time. That said, I do have some passwords so they must be for something.

So my questions:
- Is it possible to have a multibit classic wallet without a password or am I just wrong?
- Can backup wallets have different passwords?
- What are my options? I have seed words but trying just now on another app they seem to be for an empty wallet.

Thanks for any help. I can't figure out how I did it a year ago but cannot now...
