make sure you logg into the launcher with the profile you bought the game with, and also make sure that you run the game with an internet connection (only required the first time you play the full game) and that neither your firewall nor the network/router blocks the Minecraft launcher from accessing the internet.
Is Minecraft able to connect to the internet on your computer? Is it giving a warning message like "unable to logg in" or does it say something like "this account is not premium?"
Why can't I play the actually game? I hope I didn't waste my money on this
