Edited Issue: Getting COMExcpetion when attempting to register changes in a Windows 8.1 PC [11504]

I've create a task using this library, that worked.

Now when I use the TaskEdit dialog in the following way:

```
Using D As New TaskEditDialog()
Using Tsk As Task = ts.GetTask("\MyTasks\Task1")
D.Editable = True
D.RegisterTaskOnAccept = True
D.Initialize(Tsk)
End Using
End Using
```

I get a COMException with __error code -2147216615 __and a message of __(45,8):Period:__. I have noticed that if I change the __Configure For__ dropdown to Windows 7, Windows Server 2008 R2 it saves.

What am I doing wrong or does this library not support Windows 8.1 as yet?

The output from D.Task.xml is:
