Help guys Kernel32.dll

[MarkusF123]

Hey guys, i'm new to this game and unfortunately i haven't been able to play it on my pc yet. Every time i try to launch the game from steam, i get to choose DX9 and it says "sychronizing" for a second and then nothing happens. Therefore i tried to launch it from the civ 5 folder but then it tells me that there is no GetLogicalProcessorInformation in the DLL-Library Kernel32.dll.

My pc's specs:

Windows xp
Intel(R) Core(TM) Duo CPU
E4500 @2.20GHz
2.20GHz 2 GB Ram
Nvidia Geforce 8600 GT

Any help would be very much appreciated
