Hello All,

So I installed Beyong Skyrim: Bruma and it caused the crash at the startup. I thought at first it was something corrupted and did reinstall and file checks. Instead the problem was that the mod used the latest new features from version 1.6.1130. I came by a mod called Backported Extended ESL Support on Nexus. It backports those feautures to 1.6.659. After installing it, I was able to start the game and play it without any problem.

Regards,
Ozan
