This solution should be used after all appropriate troubleshooting resources have been used.
Detailed instructions

Auto Data Recovery may help recover your data in one of two ways:

Recreate lost transactions using your current Transaction Log file and a copy of your Company file.
Recreate all but the last few hours of transactions with a copy of both your Company file and your Transaction Log file.
