ticounne's right, you need to patch Infinite before entering the serials. You don't need the installation code, just your Vue5 serial, and after that you need to type in each module's serial when asked to. Worked for me too. If you have 5 esprit and the modules, you are registered already. I don' t really understand what's the problem here. Do you mean you didn't register the xtra modules? Please be more specific, as the process of typing serials for Infinite is very boring, I agree, but easy.
