HelpHDWC File is changed???

so i got this error after i patched the game, it pops up when the hdwc is at like part 7
"HDWC file is changed : W[2007] L[0] rez/RB001.REZ"
how do i fix it ><

Get a backup file ;o. I have clean backup file for it. It seems like you are missing a rez file. check your rez files, it goes from rf001-rf120. RB001 is also supposed to be there
