I'm really new at this, I'm trying to figure out how to do this.

To use this exe you must recompile your logon server so the following line in login_server.c

Code:
*const char *PSO_CLIENT_VER_STRING = "TethVer12510";

says

Code:
*const char *PSO_CLIENT_VER_STRING = "TethVer12513";

any help would be greatly appreciated.

Hi shuck, you are clearly new here but please in the future don't post about Tethealla related issues here. Especially the same issue twice and in the wrong board. It seems rather like you're impatiently wanting to use a gaming community's forum for technical advice before leaving again.

If I were you I would direct your queries to http://www.pioneer2.net/phpBB3/index.php

That being said, your issue looks remarkably simple, to the point where opening an English language dictionary would have solved it.

Just open the file "login_server.c" in a text editor, Ctrl F to find the first string, replace it with the second, and then recompile with, say, Microsoft Visual Studio.
