====== Subpage Not Showing - iViewer======
===== Problem =====
Subpages arent showing as expected in iViewer, but are showing correctly in guiDesigner.

===== Solution =====
This can be caused by the license registration code not being added to guiDesigner. Ensure you have the license added into the gui file as per the following:

  - Click on ''File'' then ''Manage Devices''
  - Enter the name of the device (use the same name entered in step 6 to help you remember 
  - which device the registration code belongs to and which devices you have 
  - registered  the  GUI  for) 
  - Paste  the  registration  code  into  the Registration Code text box on the Manage Devices dialog
