xeon cpu, same here, e5440. and with a day of search i found the problem, the cpu.
sse4.1 or vt microcode missing. i am not an expert in this bios flashing and microcodes :D but i found a very good page here: http://genius239239.myweb.hinet.net/771/
tell this thing to an expert or try it yourself but be carefull. i save my current bios and i have dual bios, this is why i try tis myself. :D very risky.
but now, the game run fine.
i download my motherboard modded bios from this site and flash the bios and now i have sse4.1 and vt and the game run fine.
