When you puchase a license through PayPal there is usually a few days delay before I receive the confirmation and send you a license.  This delay is because I don't check my E-mail everyday.

When you get your license number it is important that you enter it into Picture Slots exactly as you received it.  It is case sensitive!

The license is made up of two parts, 1) Your name, and 2) You license number.  The easiest way to get them into Picture Slots is to select the License Number from the E-mail I sent you and right click on it (or press Ctrl C) and copy it.  Don't bother copying your name because I assume you can remember what it is.

Load Picture Slots and click on "Configure".  Type your name as it is written in the E-mail into the name field.  Then right click in the License Number field and select "Paste".  Click the appropriate button and you are done.
