I downloaded iguana and logged in with seed. But it does not show the kmd.
If the address is correct but the balance shows: - it's a known bug, I suppose you're in Basilisk mode, isn't it? You can check the address balance with an online explorer:
http://kmd.explorer.supernet.org/ if it's there your coins are safe on the blockchain. Try restarting Iguana or wait some minutes.
Is it normal to not appear?
