Ok thanks I will follow your instructions guys.
My seed is correct 100%. No 2fa. I can't really import my old wallet. And when Im typing my bitcoin address instead that's the time NEXT button will be enabled.
Typing bitcoin address? There's no field for bitcoin address on Seed restoring. Looks like you hit the wrong directory of instead of choosing "Standard Wallet" , you choose "Import Bitcoin Address" or something term like that.
You must hit "Standard Wallet" then choose "I Have a Seed" and that's it. Or if my term is incorrect you can basically follow it based on my statement. Then wait for it to synchronized. Although Im not sure if the "Label" will also be restored but it doesn't matter after all as you can reviewed your Labeling on your old electrum wallet as it's not yet uninstalled on your old PC.
EDIT:
In that case you are probably clicking the wrong Option, should be something like New Wallet - Restore from recovery seed or something similar. If you are clicking from "Watch address" or something similar, it will not accept the seed at all. Is it possible that you could send a screenshot of the window where you enter the seed? Of course without the seed or it censored.
Oh there's already a reply within a sec of my post. Yes that is also my view and OP may hit the wrong option.
