That
mbexport tool you linked to does not export
keys from MultibitHD wallets... it only exports the
seed mnemonic...
For Multibit HD, it will look like:
MultibitHD wallet opened
Enter your passphrase: ***
measure swim globe radio reunion awful reflect tail produce treat cluster spot
Interestingly... if I create a normal MBHD wallet using a "normal" 12 word seed:
best achieve monster virus humor soon spin result knock actress churn design
And then run the extract tool on that wallet, as expected, the tool returns the same 12 word seed:
MultibitHD wallet opened
Enter your passphrase: **********
best achieve monster virus humor soon spin result knock actress churn design
However, then I restored the wallet as a "BETA 7" (aka 'not BIP32 compliant') version
using the instructions here, (I used the same 12 word seed mnemonic of "best achieve monster virus humor soon spin result knock actress churn design")... this time the tool extracts the seed from the wallet file as:
MultibitHD wallet opened
Enter your passphrase: **********

I tried putting that super long (48 words!) seed mnemonic into Electrum (as BIP39 and using path m/0') and even though it said "checksum failed", it actually created the same addresses as the BETA 7 wallet! I double checked with Ian Coleman's tool (BIP32 tab + custom derivation path - "Multibit HD") and it generates the same addresses on that as well:

Perhaps this might be a solution to access the private keys and coins?
