When reconciling one of my savings accounts I found it was out by $400. So I went back looking for missing or duplicated transactions. What I found was a payment of $1000 which only reduced the balance by $600. Ok some sort of file corruption, so I went to the file operations menu and validated the file. What I had then was a file of accounts that I hadn't used for a decade with rubbish balances. When I open one of the accounts the transactions are from a different account altogether. Is there a way to recover from this? I discovered to my horror that I hadn't taken a backup for 2 weeks.
