Please help me

Hi is there any thread for fixing the problem?
When I clicked the start on the launcher, it opened the game screen for few seconds and went right back to the launcher. No error messages poped up.
I've found some people in the forum encountering same problem, but i couldn't find any solution.
Please let me know if there's a way to fix this.

 

I solved (Sorry for my bad english)
Step 1: Copy your Paz its in your game and crate new file copy paste in new file
Step 2:http://forum.gameznetwork.com/threads/download-mirrors-client-patch-v760-community-provided.210022/ download full patch 30 gb but dont download paz you already have (You can do this torrent easy you can chose)
Step3:And copy next to paz in new file
