erreur lors du lancement du jeu

Bonjour,
je viens d'acheter et d'installer Minecraft sur pc mais le soucis est que lorsque j'appuie sur "play" rien ne se passe. Alors je regarde le "launcher log" et celui-ci m'indique plusieurs erreurs... comment ces erreur sont-elles réparables ?
Et voici ce qui est écrit dans le launcher log :

Je vous remercie d'avance.

 

Excusez moi pour cette erreur certes j'ai du me tromper mais après ce n'est pas "LE" soucis puisque ce n'était qu'une faute de frappe et que j'ai pu me connecter, cependant, mon problème vient plus de :

-[17:44:39 ERROR]: Couldn't save profiles before logging in!

-[17:45:08 ERROR]: Couldn't save profiles after logging in!
java.io.FileNotFoundException: C:\Users\asus\AppData\Roaming\.minecraft\launcher_profiles.json (Accès refusé)

-[17:45:10 ERROR]: Couldn't save version info to install PartialVersion{id='1.8.1', updateTime=Mon Nov 24 15:13:31 CET 2014, releaseTime=Mon Nov 24 15:13:31 CET 2014, type=RELEASE}

Et tout cela rien qu'en le téléchargeant et l'installant après facturation sur le site officiel de minecraft...

Et je vous remercie pour votre réponse.

 

Tout fonctionne !!!
Je vous remercie beaucoup !
