I know you're already passed this part, but when they say "go to settings" they mean in the Storm 8 game you chose, not the TL game you're trying to transfer. In a Storm 8 game, the settings button looks like a Cog Wheel. I transferred without an issue via World War from my old Android phone to my new iPhone 5 on XMAS day and it only took 3 minutes.
I'm not sure if it will still work for you or not, but you can try doing the transfer again with the steps in Post 1 by using World War Storm 8 game.
