Error load in additional sources

Hello.

I have problem with download page and its sources. 

For example

GET http://localhost/Apps/Shell/styles/GridStyle.css?v=9.2.1.1230
default.aspx:27  GET http://localhost/Apps/Shell/EPi/Shell/Light/Shell-ext.css?v=9.2.1.1230
default.aspx:105 GET http://localhost/Apps/Shell/Scripts/ext/ext-base.js?v=9.2.1.1230
default.aspx:107 GET http://localhost/Apps/Shell/Scripts/Shell/mainLayout.js?v=9.2.1.1230
default.aspx:28 GET http://localhost/Apps/Shell/Scripts/Shell/ManagementClient2.js?v=9.2.1.1230
default.aspx:44 Uncaught ReferenceError: ManagementClient is not defined(anonymous function) @ default.aspx:44
default.aspx:106 GET http://localhost/Apps/Shell/Scripts/ext/ext-all.js?v=9.2.1.1230
default.aspx:114 GET http://localhost/Apps/Shell/styles/css/Shell/mainLeftTemplate.css?v=9.2.1.1230
default.aspx:114 GET http://localhost/Apps/Shell/Scripts/Shell/mainLeftTemplate.js?v=9.2.1.1230
default.aspx:108 GET http://localhost/Apps/Shell/Scripts/Shell/mainHistory.js?v=9.2.1.1230
default.aspx:111 Uncaught TypeError: Cannot set property 'MenuCount' of undefined(anonymous function) @ default.aspx:111
default.aspx:346 Uncaught TypeError: Cannot set property 'Views' of undefined(anonymous function) @ default.aspx:346
default.aspx:52 Uncaught ReferenceError: validateUrl is not defined

http://localhost/Apps/ - I think, that problem in this part. But how i can solved this problem?

p.s. Sometimes it's works, page loads, but very often page does not load and I see indicator "LOADING"

Thank you very much in advance.))
