UPDATE: Every PC I used to find problem had window10, so this time I tried logging in with windows 8.1& dx9. Surprisingly, I was able to exit the loading without error, and even succeeded to escape from lakeland. I tested it only for a short time so idk if the problem is completely solved. Maybe the same error may occur again if I stay logged in for a long time, or log in with windows 10. Hope this helps!
