The problem of Git in starting

Hi , Git engineer,

Thanks for your gift of Git so much excellent .

But after I downloaded this Git-1[1].7.3.1-preview20101002.exe ,

I installed this version Git , but when I started Git->Git GUI , and

problem happened , this problem screen picture is put the attached file  ,

and then can't start Git , I have to exit the Git and can't continue to do anything in Git ..

(See attached file: 1.JPG)

This problem always happened , whatever I uninstalled Git and reinstalled Git many times ,

Now I doubt if need to reinstalled Window XP OS .

Would you tell me how to solve this problem , and let me use Git normally in Window XP OS ,

Thanks
