This document contains answers to frequently asked questions about an application called MBA. The questions and answers cover issues like errors loading required DLL files when using Tesseract optical character recognition, the application suddenly closing in Tesseract mode, receiving timeout errors during bruteforcing, restrictions on the number of open TCP connections in certain Windows operating systems, and how to disable flickering of the graphical interface in different Windows versions.

1. MBA FAQ
Q) When i run OCR in Tesseract mode, i always get "Image not recognized" error
regardless of the captcha.
A) This means that MBA was unable to load Tess.dll. Tess.dll requires
msvcr90.dll and msvcp90.dll. These DLLs comes with Microsoft Visual C++ 2008
Runtme. So the solution is simple: go to the Microsoft site and download the
Runtime package.
Q) As soon as i try to recognize an image in Tesseract mode, MBA suddenly closes
without error messages.
A) Then maybe you have installed Tesseract 3.0. Removing Tesseract 3.0 does not
solve the problem. You need instead to open the Environment variables panel
(from control panel -> system -> advanced settings), remove the Environment
variable TESSDATA_PREFIX and finally restart your system.
Moreover you can get this behaviour if the OCR profile you loaded uses a
language file not available in Tessdata directory located in MBA root. In this
case just try switching the language file and check if your Tessdata directory
is corrupted, i.e. try redownloading MBA.
Q) When i start bruteforcing, after some time i get only "404 - TCP connection
timeout" errors.
A) Then maybe your OS is limiting the maximum number of half open TCP
connection. In order to work properly, MBA need this limit to be turned off.
Limit on half open TCP connections has been implemented by Microsoft on the
following OS:
WIndows XP SP2
Windows XP SP3
Windows Vista
Windows Vista SP1
If you have one of these OS, then you need to remove this limit. You can quickly
found how to patch your OS by asking your friend Google ;)
Also be sure that you don't have an active firewall that can interfere with MBA.
Sometimes allowing MBA in the firewall rules is not enough. In these cases you
have to completely remove the firewall, i.e. use a better firewall :P
And finally be sure that your connection is compatible with the number of bots
you're using. Some crappy connections and/or routers will cause MBA to not work
properly.
Q) I need to edit file x.ini of MBA. Can you explain to me the format of this
file?
A) Nope. You're not supposed to edit and/or open any .ini file that can be found
under MBA root. By doing so you can cause a program crash and/or loss of data.
Q) In MBA there is this fucking flickering. Can you fix it?
A) In order to minimize graphic corruption under Vista/Seven, i used some tricks
-> flickering is the downside. I was forced to do things this way since the
compiler i'm using is pretty old. I don't know when/if i'll upgrade compiler.
Anyway you can stop the flickering by following these instructions:
- If you're under Windows 2000/XP just uncheck the option "Enable Vista/Seven
Refresh Mode" under "General Settings" frame.
- If you're under Windows Viista/Seven uncheck the option "Enable Vista/Seven
Refresh Mode" under "General Settings" frame, close the program, right click
on .exe, select Compatibility tab and check disable visual themes. DO NOT enable
compatibility mode.
