Voilà la réponse du support konami au bout de 10 jours:
we apologize for the delay in answering you.
We have checked your account details and they seem fine. We would like you to try the following. Please do a backup of your savefiles which can be found under My Documents in the Konami Folder. Once you have made a backup to a secure location, delete the files from PES 2010 in the My Documents folder. Uninstall PES 2010 from your PC entirely and try a reinstall.
Could you kindly let this know if this has resolved the problem?
Best regards,
Your Konami Support Team
Bref ils me prennent vraiment pour un con.
J'ai renvoyé un mail pr avoir un nouveau serial car j'ai déjà tenté de reinstaller et toujours le meme probleme.
Bon y'à plus qu'à attendre 10 jours pr qu'ils daignent répondre.
