They've merged a patch that fixes this... refer:
https://github.com/fyookball/electrum/issues/6 and
https://github.com/fyookball/electrum/pull/13The catch is that you have to run from source (or compile your own) until they've actually released a new compiled version. So, if you're desperate to get the coins out, you'll need to clone or download their repo and run that way.
Also, a 2FA wallet won't work regardless... as it requires signing by TrustedCoin... who will sign it as a BTC transaction and it will get rejected by BCC network. You'll need to restore from 2FA seed and disable 2FA when prompted to "keep or disable" 2FA.
