Try this workaround. I had the same issue a while back.
I successfully tried generating a wallet in multibit HD and retrieving its extended private key using an offline copy of the webpage linked below.
https://iancoleman.github.io/bip39/Once you have the extended private key you can use it to get your Bitcoins back by importing it into a blockchain.info wallet. The page also shows a list of private keys for each address in an HD wallet, and you can import them into electrum or some other wallet to access your Bitcoins.
To use the webpage right click the link and choose save as , then press enter.
Open it offline in your browser, then click the BIP32 tab below the big Derivation Path heading.
Put the text below in the BIP32 Derivation Path box.
m/0'/0
Type your
password seed into the BIP39 Mnemonic box.
The page should automatically generate your extended private key and a list of receiving addresses for your wallet.
If your Bitcoins are in a change address then repeat the steps above, but type the text below in the BIP32 Derivation Path box.
m/0'/1
The page should show you all your change addresses with their private keys.
If aren't sure if that webpage is trustworthy it was recommended by a respected member of bitcointalk called dooglus who's a clamcoin dev, and runs a well known dice site. This is the post which he recommended it in.
