Re-uploaded the files.
Steps to follow :
1 : Download this file.
2 : Extract (aka unpack) the files into your RO folder.
3 : Overwrite all if it asks you to.
4 : Run the forsakenRO patcher.
5 : Try to run the game and see if this solved your errors.
PS. I did not include the normal client cause I don't think any client modifications were included in this update, though running the FRO patcher should update your client either way.
Regards,
Ryuk
