You need version 6.4.10 in order to use Wagemaster files in File Manager
If you have processed your pay event through STP you should not restore a file prior to the most recent STP processing date.
Your Wagemaster file needs to stay as it was when you submitted it through the STP portal in Wage Easy as this is a legal requirement.
Click on date of the file you need to restore
Click on Restore older version
If this is the file you wish to restore, click on Restore.
Wait a few seconds and the file will be restored and you can open and work on it.
