I have just got a new computer and am still having the same problem I had on my old one which was at the low end of the recommended specs for Civ 4. My new computer should be easily capable of running the game and if I can get it to start, it does run fine with no problems - but mostly it just locks up on the first screen - the one that says "Loading" in several languages. The game is patched to ver 1.52, I have downloaded all Windows updates, updated my graphics drivers and I have tried disabling all startup files without any improvement. There is never any error message - just send a message to Microsoft (which I have done) and I have enabled logging but no log files are created. I have searched through the forums but haven't found anything helpful. I have attached my dxdiag - I am really hoping someone can help (have also emailed tech support but other posts suggest I shouldn't hold my breath....).
