There's a problem with the "Bottlecaps" Coin configuration, it doesn't start the miner using the Scrypt settings, for some reason it thinks it's a SHA-256 coin.
Can you zip up the XML files in your %appdata%\MultiMiner folder and send them to me? Email is in my sig.
Edit: No need - reproduced and looking into it.
Edit 2: I'll be posting a fix soon but you can fix this for now by editing the CoinConfigurations.xml manually
Edit 3: Fix is live! Thanks for this!
