Ebola 2 error?

[valam]

The problem is that I think the game is defective, I've already looked around the forums and nothing. The game projects a pattern of piano keys on a radio, I go to the piano and manage to obtain the same
pattern but the secret door does not activate. I have tried everything and I have spent days figuring out how to achieve it and nothing. I have seen several videos on YouTube and in all of them the radio projects a pattern of numbers and then it goes to the piano and the keys represent numbers, then the numerical pattern is placed and that's it, the secret hatch opens. I didn't find any video where the pattern is piano keys.
Greetings, I hope you can help me.

Hello. This may be due to some error when installing the game. You need to reinstall the game. (don't forget to leave your saves in a secluded place so you don't have to play the game from the very beginning)

If reinstalling the game doesn't help. Try to turn on the game, set all graphics settings to minimum, and check this place, then, in the same order, set the game settings to maximum and check this place.
