Once you receive your license key by email, either:

• Copy the License URL and paste it into the URL field of your browser. Tap the enter key. When it asks if you want to open iWatermark then tap ‘Agree’. It will open a dialog asking you to apply the license or that you are registered.
• Or manually copy and paste the license key into the app you purchased and hit the ‘Apply Registration’ button.

If you have any problem make sure to:

• Find and carefully read the email we sent automatically after your purchase.
• Use the URL in the license info to apply the license info or manually enter the license info
• If you manually enter the license and have an issue, make sure to: 
  • Copy and paste to avoid mistakes
  • Use the info in the license not some other email, etc. That won’t work
  • Be careful not to add extra characters or change any info
