Memoriax

Finally I manage to log on again by checking compatibility with Windows 8.1 before launching PRO. The patch can't still be downloaded but I manage to play. Don't know why ...

Thanks for your reply. My OS is Windows 8.1 64 bits. PRO ran perfectly before the patch, so I don't understand why it should not run now. The problem comes when running the PROClient.exe. The message says "downloading patch ..." and then "failed to validate patch", even though internet connection is OK.

Still impossible to connect with the same message "failed to validate patch" when launching PROClient.exe. Internet connexion is OK. Any solution?

Hi everyone, When launching PROClient.exe, the error message "Failed to validate patch" appears. After that, I can't log onto PRO with my login & password. A message suggests downloading the last PRO version: I did it but nothing has changed. How can I solve this to play PRO again? Maybe other players faced the same problem. Memoriax
