Before today, I had one non-R2 disc, and I played that in my flashed drive with Region Killer, and it worked flawlesly. Today I received T2 UE R1 through the post and tried to play it on the PC. For some reason I got a window popping up asking me to specify the region of the disk. I cancelled it and checked the Region Killer settings. It was enabled, auto-region was on, and it had chosen R1. OK, I thought, I'll try again. Fired up Power DVD, and I get a blue screen when playing the disc. Regkill.sys is at fault. Reboot, chuck in an R2 disc, same blue screen. Removed Region Killer, rebooted, and played the R2 disc fine with no problem. Just checked my drive in Device Manager (Win XP) and it says I have 2 region changes left. Drive Info says that my drive isn't locked. I can't seem to get the latest version of RK from the official site. Anyone got any thoughts as to what's going on?
