You should of let them figure it out for themselves. If they cant fix something this easy they shouldnt be running a server. It may seem rude/cruel but its true.
I have been running servers for a very very long time and in the top ranks as well, ASM isnt everyones cup of tea considering most servers you work with dont require this form of editing.

Im trying to learn--
Please, how do I find this line in OllyDbg?
According to the MSDN the PE header is 1000 Bytes and looks something like this:
typedef struct _IMAGE_FILE_HEADER {
WORD Machine;
WORD NumberOfSections;
DWORD TimeDateStamp;
DWORD PointerToSymbolTable;
DWORD NumberOfSymbols;
WORD SizeOfOptionalHeader;
WORD Characteristics;
} IMAGE_FILE_HEADER,
*PIMAGE_FILE_HEADE
Source:

That file is in hex, and has file offset, you must calculate the virtual offset.
Virtual_Offset = (First_Address - Header) + File_Offset

So how do I do with this:
6BB51 1C E9 03 00 00
How do I find and delete the line?
Sorry I did not know that I am trying to learn is serious!

Open GameServer with Olly, scroll up till the first address use the equation posted above to calculate the address.
First_Address = 401000
Header = 1000
File_Offset = 6BB51
And you will see the rest.
- Aquilis - 10-12-2011
Virtual_Offset = (401000 - 1000) + 6BB51
Virtual_Offset = 400000 + 6BB51
Virtual_Offset = ?

This is a simple math, chapter 1 of this Book explains it all:

I got the book translated
- blankname - 10-12-2011
- open gameserver.exe with an hexeditor
- goto offset 6BB51
- replace 68 B0 BC 62 with E9 1C 03 00
