1. I already transfered my BTC to Bittrex so I dont need to create another electrum wallet for transfer.
2. I downloaded Electron Cash
3. Try to setup wallet from existing seed - Cannot press 'Next' button when trying to create.
I'm not sure what is the issue there. You should be missing a word from the seed or something like this.
You can:
a. Do like I said above and open your BTC wallet in Electron Cash
Or
b. Open your Electrum (BTC) wallet again and check if the seed you are trying to input is correct by checking if it's the same found in Wallet -> Seed.
I found the issue finally.. So it was that new electron wallet 2.9.4 did not support 2fa wallet and that is why i could not do it... I downloaded previous version and it is ok now. Thank you very much for the help!
