Because a new install didn't fix your problem i'd try this way
use another path for you install
instead of C:\ProgramFiles\alaplaya\S4League use C:\ProgramFiles\S4League or the other way round
If it won't work, try using the following HGWC.exe
i uploaded it here
VT Check is posted below
Scan: HGWC.rar
