you can restore your wallet from seed, and request a new Google Authenticator code during the restore process.
Thanks for your reply. How exactly I can restore? because when I click the exe, it opens the console and ask me to enter password which I do and it just opens up my wallet? thanks
When wallet is open then you need to click on File-New/Restore option,select option that you have a seed and that you want to create 2FA wallet.You have option to disable 2FA or keep it/in this case you need to choose option I don't have my Google Authenticator code so you can restore them.
This should solve your problem with 2FA,but be careful and keep your seed on safe place-it is only thing that can restore your wallet even if you lose your phone/2FA.
