le profil est détecter dans le launcher Minecraft mais pas la version

J'ai vu que dans le fichier "Usinacraft 2.1.0.json" , il y a écrit

<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.2.1</center>
</body>
</html>

au lieu de quelquechose du genre, du coup la version n'est pas détectée:
