Hi! There might be different reasons for this problem to occur, and so, different ways to solve it.
First, what are your computer specs? What OS do you use?
How long have you waited with the black screen?
Try to enter windowed mode when the logos appear (ALT+Enter)
Try to check the integrity of the game files:
- 1.Restart your computer and launch Steam
- 2.From a game's library page, select Manage > Properties.
- 3.Select the Local files tab and click the Verify integrity of game files... button.
- 4.Steam will verify the game's files - this process may take several minutes.
