I played allways GR not patched, witout mods. Today, I installed the "1..3"patch, then "1.4" patch (the last). But I got a crash! I reinstalled the game, and I tryed all patches...I get this crash alltime!!!! I have to reinstall the game alltime! And I understand now: I get crash after istalling a patch. Plz, help me, a little newbie! NB: I have only GR, I'll buy DS and IT later.
