Having trouble starting the game

Hi!

So I just downloaded the game to join in on the fun, but my computer won't let me :/ It keeps crashing every time I open it. it tells me:
"This application has encountered a critical error:
The system cannot find the file specified.
Program: D:/Wrath of the Lich King 3.3.5a/WoW.exe
File: ./Client.cpp
Line: 3578

File: signaturefile"
I've already tried to unmark it as read-only, but that seems like it only worsened the problem, considering I could actually open it when it was marked as read only.

Thanks!

maybe you didnt complete the downlaod at 100%, try to download the client again

hello,

kind of same problem here..

The system cannot find the file specified.

Program: D:\wow\Wrath of the Lich King 3.3.5a\WoW.exe
File: .\Client.cpp
Line: 3578

when patch is instaled, wow.exe show msg above, and luncher is "dowloading" update, and whet its done it will redirect me to battle.net aplication.. and that app want to dowload 28gb..

well, how can i fix this without dowloading another 28gb ?

you need to log-in by using your warmane account name, not email address.
if your client is not 3.3.5 anymore you need to download the wotlk client again
