In order to use this software fully you will need a valid licence key. Without a licence key you can only save, export, print or scroll the VDU chart for plans with 30 or fewer guests.
To purchase a licence key go to www.perfecttableplan.com .
To fully activate the software select Licensing>Licence and enter the key into the 
Licence window.
If you purchased the software electronically off the Internet, the key will have been emailed to you.
If you purchased the software as a CD, the licence key will either be printed inside the box or will have been emailed to you.
To retrieve a licence you have previously purchased from www.perfecttableplan.com select Licensing>Retrieve Key.
Note A standard licence entitles one named person to use this software on any number of computers. If you have more than one person using the software you should purchase a licence key for each user. However, we have no objection to a couple sharing a licence when planning their wedding. You can also purchase an organizational licence.
The same licence key will work on both Windows and Macintosh.
Version 1-4 licence keys are not valid for version 5. You can upgrade to version 5 for a small fee.
You can also upgrade your edition, e.g. from PerfectTablePlan Home edition to PerfectTablePlan Advanced edition.
