Hi marceloaa
I'm not with Laminar Research, just a fellow simmer in the UK.
In order to try and establish why your copy of X-Plane 11 'stops working' whilst loading, it might be worth uploading a copy of your X-Plane 11 Log.txt file to this post, so that I and others with a great knowledge base can review it.
If you're not sure how to up load your Log.txt file, please click on the following link to see some PowerPoint slides that I have prepared for this purpose:- http://questions.x-plane.com/?qa=blob&qa_blobid=2701300599488744382
Further, just to make sure, I would suggest checking your PC system specification against that recommended on LR's website:- https://www.x-plane.com/kb/x-plane-11-system-requirements/
