Ok, so I ran the patch yesterday and all went fine (the installation). I started Conquer and noticed the font change. I logged in to Lab4 and started hitting a Minotaur.
Half a second later, I get the blue screen of death:
I can NOT hit a monster, do a skill (cyclone e.g.) without getting that screen and my computer crashing! All I can do is jump until some other error gets me.
This all started happening since I installed that problematic patch
