When I try and send a payment from my Electrum wallet, I enter my password and then my 2fa code from Google authentication app it says "Invalid OTP". I double checked and its defiantly the correct 2fa code.

Are you sure you're loading the correct wallet file (maybe you created more than one wallet)?

Are you sure you're using the correct 2FA entry in Google Authenticator?

Have you checked that both the current time and time zone in your phone are correctly set?

If all else fails, you can restore a wallet with your seed (which you do have, right?) to recover your funds. Note that the restored wallet will not be 2FA-enabled, so you'll probably want to create a new 2FA wallet and transfer your funds over to it.

first, check that the clock of your phone is correctly synchronized.

if that does not work, you can use your seed to request a new google authenticator secret (that's new in 2.7)

I'm one of the TrustedCoin admins.

Can you clarify what you mean by "greying out".  Which specific interface element was greying out?

BTW, if you wish to continue this discussion via email feel free to reply via the TrustedCoin contact form.

Well, one of my saved seeds is 12 words and it restores just fine, the thing is that wallet balance is 0. I have another seed saved and it has 16 words, I try to restore it and when I enter the seed, the "Next" button is greyed out and cant click it to continue.

Electrum 2FA seeds have never been 16 words long.   AFAIK they've only ever been 24 words (super old versions), 25 words (versions before 2.7) or 12 words (2.7+) .   

I suspect the mnemonic you are trying to enter is from some other application?
