If you have windows xp please extract this Silkroad.exe in your diamond folder i'm using it already works very well.
Edit: Virustotal scan
Edit: Btw, this silkroad.exe is working on the whole servers based on vsro files these days.
idk where's the source but its from someone in Epvp
Edit2 : >> here is the source its for bsro, but since diamond sro has the same files so it works
