Thank you for uploading the error report. It's unusual for a critical failure to occur during send operations so we'll take a look and add any notes to this issue.

I think the problem is in saving the wallet rather than in the send. It's this stack track:

There is an 'access is denied' in the above which suggests something like a file lock that isn't released or something similar.

If your wallet is a regular MultiBit HD wallet, rather than a Trezor wallet, to retrieve your bitcoins the simplest way will be to: 1) Download lighthouse from https://www.vinumeris.com/lighthouse 2) Create a new wallet using your wallet words (they are compatible) 3) Wait for the wallet to sync and then empty the wallet to whereever you want.

Thank you for the help, it's very much appreciated.

Hello, I have the same problem and after installing and running lighthouse the only thing multibit asked me to do was to send this new wallet the existing balance, but it all appeared to be zero. This transaction has now more than 2 hours since placed and it's still on error, C'mon I need to complete this transaction.

when I'm installing the lighthouse software it does not allow me to restore my multibit wallet in order to sync it with this one,

Finally it worked, and thanks so much for your comment
