How the heck did you come up with this?!
They said earlier another genesis block will need to be imported.
how is this done?
Don't take what I say for granted, but after release they will provide new genesis.
You import it with:
Personally I will completely delete %userprofile%\Appdata\Roaming\Expanse folder
(it is usually c:\users\YOURUSERPROFILE\Appdata\Roaming\Expanse)
regardless if they put it in the instructions or not - that will require creating a new EXP address.
Actually I think a new required anyway (I highly doubt if you can use a testnet address in the main network)
