We posted at the same time (well I edited my previous post ). Once again, many thanks for the information. Thanks to your explanation how you patched/fixed the .exe, I managed to patch the modified COD2mp_s.exe by Mitch by myself. But just to be safe, I rather use your patched exe because I have no experience in this and I don't know if I edited it correctly. My edited exe is attached in my previous post btw.
Server functions seem to be in working order (I can connect, walk around, shoot etc), but I don't know if it actually blocks the exploit because I don't know how to execute it.
Once again, many many thanks!
