I couldn't load any gamemode scripts. Please verify your server.cfg It needs a gamemode0 line at the very least.

The gamemode he's trying to load doesn't exist. Is your friend sure that he compiled the gamemode so he can get the .amx file?

The localhost will work if samp-server.exe is running and it's not like the above case (without giving run time error).
