To restore the panel you removed, please, try the following steps:
Go to main menu command [View -> Panels] and select required panel in drop-down list
If the panel doesn’t appear, go to the folder with the product, open ‘Dsk’ folder and delete a file that has ‘dock’ at the end of its name. For example, if you use VIP Organizer, you should go to C:\Program Files\VIP Quality Software\VIP Organizer\Dsk and delete ‘VIP Organizer_dock.dsk’ file.
If the previous actions didn’t help, go to C:\Program Files\VIP Quality Software\VIP Organizer\Dsk (for VIP Organizer) and delete all files from this folder
