We have an unpacked DLL file which is loaded through an exported function. This function seems to be the main one in the authentication process but there are other functions in the DLL file which could also check the authenticity of the user. The DLL file can be used from a Metatrader EA (mq4 file). So our requirement is as follows: remove authentication restrictions from the DLL file. That is, after the changes the DLL file must be fully functional without authentication. So the DLL file and all its functions must operate as if the user had entered valid credentials. We will provide more details to those interested in the project.
