Minecraft when I open it from Minecraft Launcher gets stuck just before fully loading on the red screen, as it shows it is NOT RESPONDING and CRASHES.
I have also just purchased the game and this is extremly dissapointing as I have payed for the game digitally yet have not been able to play it.
This appears to be a technical support issue and the bug tracker does not have the appropriate resources to help you with this problem. Instead, I'd highly recommend contacting Community Support in order to get your issue resolved.
