I´ve DLL Source Code (PASCAL), need PROFI to clean the mess!

I need an expert for DLL because my (SMALL) source code is a mess (I think so) Someone have created a kind of protection for me! Let me explain how it works: I have an EA (Expert Advisor) written in mq4 language, this EA has a code inside with #import function! That means that he receive data from a DLL! this protection works as following: I have a kind of control panel where I can add username and password, this username and password will automatically record in a MySQL Database! Then i give customer the Software and after he typed in username and password, the EA connect to the server....! If the username and password are correct then the EA works! But some users get MT4 Crashes and error messages so there must be a problem anywhere, I don´t know where the problem could come from! There are 4 possibilities where the problem could come from: 1. code in mq4 is a mess 2. code in DLL is a mess 3. something in php files from FTP Server is wrong or code is a mess 4. database is a mess In my opinion the problem could only come from DLL or PHP files, because a mq4 guru checked already the code in the EA and he means that the mq4 code looks ok! So I need an expert who can check the (SMALL) source code from DLL and clean it if the code is not coded correctly! If you´re able to make the whole job, so that means, CHECK THE COMPLETE procedure (mq4, dll, php, database) then it´s really good! But if you only an expert for the DLL it´s also OK, because I must find where the error comes from, step by step!
