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 Bob Pang
