Hi, I can help you with this. Maybe you can pm me a more detailed information about the source code. These are some question that will help me understand your project better :
1. Is it use any third party component. If the answer is yes, do you have the source code for these component.
2. Do you have all the source code or for some unit you only had "dcu". If you don't have all the unit, which delphi version used to compile the application ?
3. Can you give some description about the "bug" which needed to be solved?
I believe I can solve your problem whatever it is but without more information, but these information may help me finish faster and maybe cheaper
