[Help Launching Client 6.2.3]

Hello guys, I have this problem, download one Wow client from MEGA but when download it, I see that is patched for Firestorm servers, client ver 6.2.3 (20779), when saw this problem search in google for a wow.exe not patched and found in Azerothica.com 6.2.4 and 6.1.2 then I used conection_patcher (IN LINUX) in file 6.2.4 using the 6.0.4 TDB, the program patch the EXEs files without errors and generated Wow-patched.exe fine, both exes x86 and x64 files, BUT when launch it:

World of Warcraft no ha podido cargar la dirección de la fuente de datos de la red. Para solucionar este problema, por favor, visita https://battle.net/support/article/7413.

 

I read in the Trinity forums about some commands: 

-uid wow_engb

-uid wow_eses

-uid plsnopatch -noautolaunch64bit 

-uid wow_enus –noautoupdate

-uid wow_eses –noautoupdate

When use it each one, get this other error always:

This application has encountered a critical error:

ERROR #121 (0x85100079) Version Mismatch

Program: D:\Games PC\WoWWoD\Wow-64.exe

ProcessID: 2896

DBFilesClient\Cfg_Configs.db2 has wrong row size [found 24, expected

20)

Press OK to terminate the application.

Please someone help me, I’am from Cuba and can’t redownload the game because don’t have internet easy and is very expensive 2 dollar by 1 Hour, tell me if is necessary being online to play it with Trinity core servers, or what I have to do. Thanks for read
