Symfony2新项目不加载资源

Yesterday in this question I had a problem where Symfony2 new project doesn't load css and images. Here's the image to the problem: enter image description here

The solution given by @binzram was to php app/console assets:install web, and it worked. However, when I tried to access the page today I saw the same old no-resource config page again, and this time assets:install web doesn't do any good to me. Can anyone help me please? Thanks a lot. I'm new to Symfony2 and am really appreciate your help.

A little background:

PHP 5.5
Apache 2.4
Windows 8
