Error while syncing blocks

Hey guys,
Love what you are doing!

But I get this error while trying to sync blocks from the existing blockchain.

block_tx 62 63
block_tx 63 64

Any idea why?
Thanks in advance!

We'd need to see your blockchain in order to be able to debug this. If that's an option, please stop your node, zip up your blockchain directory, then send it to multichain dot debug at gmail dot com.

I already sent you my blockchain dir via email. Please take a look.
