After Install 2.0 No style

After installing 2.0 I do not have any style on main page or any sub pages.

Thanks

Could you please get the latest version (CodePlex) and confirm that the issue is fixed?

After getting latest I get

•Setup failed: System.InvalidOperationException: Sequence contains more than one element at System.Linq.Enumerable.Single[TSource](IEnumerable`1 source) at System.Linq.Queryable.Single[TSource](IQueryable`1 source) at Nop.Services.Installation.InstallationService.InstallSettings() in C:\Users\R2\Downloads\nopcommerce-3095cfd1dc55\nopCommerce_3095cfd1dc55\src\Libraries\Nop.Services\Installation\InstallationService.cs:line 4488 at Nop.Services.Installation.InstallationService.InstallData(String defaultUserEmail, String defaultUserPassword, Boolean installSampleData) in C:\Users\R2\Downloads\nopcommerce-3095cfd1dc55\nopCommerce_3095cfd1dc55\src\Libraries\Nop.Services\Installation\InstallationService.cs:line 9048 at Nop.Web.Controllers.InstallController.Index(InstallModel model) in C:\Users\R2\Downloads\nopcommerce-3095cfd1dc55\nopCommerce_3095cfd1dc55\src\Presentation\Nop.Web\Controllers\InstallController.cs:line 378
