From a (very) quick look at it, it seems like it is designed to generate n-of-m MultiSig addresses... so it starts generating "Pay to Script Hash" aka P2SH addresses starting with a 3... as opposed to the more common "Pay to PubKey Hash" aka P2PKH addresses that start with a 1...
The upshot of all this, is that you can't just import the wallet words or Bip32 Master privkey from mSigna to another wallet... or at least, I don't think you can... as the requirements for spending from a ScriptHash address are that "the recipient must provide a script matching the script hash and data which makes the script evaluate to true."
I think your best bet is to just create a new wallet using a more "user-friendly" wallet like Electrum... and then just send all your coins from mSIGNA to an address in your new wallet.
This sounds right....
Unfortunately I have an unconfirmed transaction so I'm gonna have to wait a week to be able to send bitcoin again!
