Once Labeljoy has been purchased and activated, it needs an internet connection to keep its activation data alive.
If it cannot connect to the internet, after a few days it will display this window to enable you to connect to the internet avoiding losing your activation settings.
You can choose between 3 types of actions:
Connect your PC to the internet and click the Check button to process activation data and keep your activation data alive so that you can go back to working regularly.
Revert to Demo mode and lose your activation data.
This will require you to re-enter registration data once an internet connection has been established, but will enable you to keep editing, without losing your data.
Quit the program and wait for a future time when an internet connection is available.
