restore your 2fa wallet from seed, don't set a password so that it doesn't encrypt the xprvs and then view the wallet file in nano, vi, or some other text editor. then restore your multisig wallet using those xprvs. file > new/restore, enter a meaningful name like multisig-restore-20171031, wallet type multisig, select the number of cosigners (2?) and the number of sigs (1?), then for each cosigner select use public or private keys and enter the xprv one at a time. after that you should be able to spend your bitcoins to another wallet of your choice. for example a new standard electrum wallet (file>new/restore again).
