So basically yesterdaynight I had absolutely no problem running the game. This morning I started the updater and:
1st - it finished checking files, but after I clicked 'start', it showed 'problem downloading files, check internet connection' (obviously my internet connections works)
2nd - checked again, then it showed some critical error and immediately went down without letting me read the crit error message
3rd - checked again, then it showed 'L2.bin stopped working'
4th - checked again, now it just opens the loading screen, does nothing for a while and then gets shut down with no message whatsoever.
Any idea what to do with it? I'm pretty sure this problem is solved in russian, but unfortunately I'm not the 'master nation' here :(
/edit: It's not in http://forum.averia.ws/threads/technical-support-complete-guide.46745/
It might be explained in russian topic, but I can't neither find or understand it.
