The following error can occur in Enhanced Windows Backup v1.1.1006. It is a known issue and will be fixed in a future release.

When working on jobs in the list, the following fatal error can occur.

InvalidArgument=Value of '1' is not valid for 'index'.
Parameter name: index

   at System.Windows.Forms.ListViewItem.ListViewSubItemCollection.get_Item(Int32 index)
   at EWBackup.ListViewItemComparer.Compare(Object x, Object y)

   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

The problem is caused by a discrepancy in the ListView Control's view of the list of jobs and EWBackups list of jobs. Stopping and restarting the program may solve the problem but if it doesn't, then you can delete the configuration file

C:\Documents and Settings\All Users\Application Data\SoftSwift\EWB_Config.xml

When you next run EWBackup you will need to re-create the backup jobs.
