you suck jk

You've messed up something on kro+rms files or lack some updates since the client is trying to get something that doesn't exist.
Better advice I can give to you is to get a clean folder, add kro to it, update using rsu patches [yes, both exe] and then add rms files.
I got that error once at another server and was because I had messed files from kro with the small client of the server.
PS - I hope you're not using rro's files and just added the rms files to that folder because it never worked fine in here :<
