Unfortunately Electrum only allows importing a multi-signature wallet as a watch only one.
Did you try to import the Bitcoin address? That doesn't work.
I only have two passwords written down.
I assume you mean private keys, right?
Try this:
Get Electrum, create a new Wallet > choose a name > Multi-signature wallet > 2 cosigners > I'm not sure how to continue. I wrote a post on
recovering Forkcoins out of multisig using Electrum (Forks). See if it's any use.
