Not sure if this has been covered before, if so I apologize, but I've found a possible solution to some of the graph_bs\... errors. A while back I posted in this thread when I first encountered the error, and a fresh reinstall from a different source fixed it. However, I recently encountered the problem again at a different point in the story. I was worried that the different source, too, was corrupt. I tried a reinstall using the same source, and encountered the same error on the Japanese .exe (before patching to English but after the bugfix patch). Fortunately, I came across this solution: setting my system to Japanese locale alone was not enough, I needed to set the Region and Language format to Japanese as well (in the same area of the control panel, first tab). After setting both to Japanese, I no longer encounter the error, even after patching to English v 1.2. Not sure if this is common knowledge or not, just hoping to help. I'm running Win 7 64 bit.
tl;dr: Certain graph_bs\... errors could be caused by not having both system locale and Region and Language formats set to Japanese.
