Okay, to set up a cityrp server make a text document called cityrp in your blockland folder.
Type:
@echo off
del blockland.exe
echo Setting up cityrp
Save this file as cityrp.bat and make sure it's in your blockland folder.
Run it, then run dedicated.bat and you should have a cityrp server.
huehuehue
Though it really just deletes the blockland program, but that should be fairly obvious.
