The fact that you see a screen with the choices "Internet Activation" or "Manual Activation" indicates either the computer is not connected to the internet or is connected through a Proxy Server that could block activation.
In this case you should do "Manual Activation".
Follow these steps...
- Disconnect your computer from the internet.
- Run GBTimelapse
- Select the "Help/Product License menu"
- Click Activate
- You should see the "Select Activation Type" window
- Write down the Request Number from that screen.
- Go to a computer with an internet connection
- Go to this page in your browser https://www.safeactivation.com/activate.php?x=21002024
- Enter your contact information, serial number and the Request Number
- It will display an Activation Code
- Go back to the first computer and enter the Activation Code
