I'm using MultiBit and my wallet balance is showing as unconfirmed. The last transaction I made was a couple of months ago and seemed to be fine (https://blockchain.info/tx-index/25339607f1d5e3f36cd964554fd85c399c9359e58b169d6b7028b3627ef74f12).
When I try to make a payment with the unconfirmed funds I'm told "The error was insufficient money, missing XXX satoshis..."
I can see the correct balance in MultiBit but it is unconfirmed. The confirmed balance appears to be Zero. Any insight on what might have happened here or how I can fix it? I should say that I'm synced to the network and have 10 peers showing. Thanks for any help
