Loading Problem

[AxelBriche]

Hello, I have a problem (sorry for my english, I am french) :

In my appKernel, I have :
new Mylen\JQueryFileUploadBundle\JQueryFileUploadBundle(),
new Mylen\JQueryFileUploadSandbox\JQueryFileUploadSandbox(),

But I have this error:
FileLoaderLoadException: Cannot import resource "@JQueryFileUploadBundle/Resources/config/parameters.yml" from "C:\wamp\www\Project_V1\Symfony\app/config\config.yml". Make sure the "JQueryFileUploadBundle/Resources/config/parameters.yml" bundle is correctly registered and loaded in the application kernel class.

My composer.json:
"mylen/jquery-file-upload-bundle":"*"

The bundle is in my vendor:

My routing:
event_flow_analyser:
resource: "@JQueryFileUploadSandbox/Controller/"
type: annotation
prefix: /{game}/TEST

Do you know where is the problem please? Thanks.
