Unpacking problem

Thanks, but the file that needs altering is the main Paltalk.exe, I know the Palnet.exe serves up the adds, but what you have to do is delete the Palnet.exe file altogether, then change the code in Paltalk.exe where it gives the error message about not finding Palnet.exe.
I tried manually unpacking Paltalk.exe in Olly, but got lost somewhere along the way.
