Hi Josh

This forum is best for pointing users in the right direction, not necessarily giving the explicit instructions because it can depend on the exact state of your data.

To recover a batch, go to Maintenance | Recover Batch. Once the batch is recovered, highlight it, click on Copy, uncheck all of the boxes except for Move entries and Reverse batch, and click OK.

You might want to press F1 for Help, or use Help | Readme
