I see some "Mauvais captcha" and "Recaptcha failed" messages, all for fileserve.com. This probably means you didn't give a correct response to those captcha challenges. Captchas are becoming more difficult for most humans but there are solutions.
Since fileserve.com uses reCaptcha I would recommend using the
recaptcha anticaptcha method if you aren't already using it.
If you've difficulties with other captchas as well I would recommend using the "
addon for decaptcher.com service". This is a paying service.
Do you have a fully updated jD? Do you have the latest fileserve.com plugin version (13003)?
