To reset downloads, check any applicable "Reset" checkboxes, then click the
"Reset Selected Downloads" button. Check the "Send Email to Buyer" checkbox to send buyer notification of reset.
When you reset any download, the sale will auto unlock (if it was locked previous), so you don't need to unlock the sale separately. However, if you have the "Lock Sales Page if More Than XX Download IP Addresses are Detected" option
enabled in the
settings, you must also delete the history to prevent the sale re-locking when the download is clicked.
