If you get disconnected from your internet so hurry up to save your open model because the license in your software will continue working in only 7 minuets and thereafter it will go to the demo mode and you will not be able to save the model.
After 7 minutes even if you reconnect to the internet again your software will stay in the demo mode and you will not be able to reconnected to the license again. And you have to restart the software again to get the license.
But if you reconnect to the internet again during 7 minutes your software will continue being connected to the license and continue working.
