HGWC displayed an error while S4 League game is played

Hi,
I tried to play my S4 League game but when I started it, HGWC gave an error message (see below).

HGWC
File is changed : W[2007]L[0]
S4Client.exe
I tried reinstalling S4, but the error wouldn’t go away.
I really love S4 games, so please help me resolve the error.
I don’t know what to do next.
Thanks in advance.
