I didn't make it!
So here's the deal:
I've downloaded one of the latest "ABC" mods which was patched (patch v1.0004), but I still can't start a new game. I've done everything like it was said in readme.txt. At first I couldn't even launch the game. "Asus" logo and then I'm back to my desktop :( Later (when I've downloaded 3 or 4 stalker game updates (now's v10004)) I could access the menu, but as only I tried starting a new game or loading an old one, it crashed (again) and now it's the latest news... :\ if someone knows what's the problem (I mean if there's something I have missed), please, don't hesitate.
