Same problem here. The issue alternates between one of 3 things:

1. As soon as I accept the terms and conditions of the transfer I receive the error, "There are no characters available for World Transfer".
2. After I accept the terms and conditions, I am able to choose a destination world, but there are no worlds listed in the "Current World and Character Selection" section.
3. During impact #2 I attempt to confirm my selection for the destination world to see if characters will then appear in the Current section, and I receive the error "There are no characters available for World Transfer".

I'm sure they're working on it. Just want to make sure I can transfer before the server I want closes...
