Reverse engineer/decompile an MT4 EA and DLL

I found this project previously posted and I have the exact same need and project. This project requires to modify a DLL used with an EA in Metatrader. Some of the limitations that has to be worked on are: 1. Removing the account license limitation, 2. Enable the usage of this EA with any MT4 broker and account number (this EA currently only works with ONE specific broker and account number) 3. To enable the back testing of this EA. At the end of this project, the DLL is modified and used together with the EA functioning normally with no broker restriction and back testing enabled. I have a valid license for the software, however I want to be able to run it on a different broker and would like to see a detailed summary of its back testing. Fix must work on both real and demo accounts. More details including source files provided by PM.
