Hi. Can someone help me please? Im on 3.3.4. on a mac

I need to send my bitcoins but dont have access to my 2fa any longer.

I followed instructions here: https://electrum.readthedocs.io/en/latest/2fa.html#restoring-from-seed

I go to file > restore / new and it says wallet 1 - this file does not exist so I choose my default wallet with my btc in. 

It then says "file already open in memory click next to create/focus window."

What does this mean?

Now I dont know what to do.  Am I doing it right so far?

I have my seed.
