Page Management in DNN 7 suddenly stopped working.  Rather than having a hierarchy in a tree, only two nodes show while there should be dozens and dozens of nodes appearing.  Thee two nodes that do appear have the (+) sign to expand, but they don't expand.

Exactly the same behavior happens in the CKEditor when browsing the server.

A forum suggested uninstalling the Page Managment module from DNN, then installing the Page Management module from DNN Werks.  Now, the following error appears:

Error: dnnWerk.Pages is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: R:\- Existence\Right Angle\- Public\Sites\rightanglecompanies.com\Versions\New Year 13\Working\DesktopModules\Admin\dnnWerk.Pages\View.ascx.vb(487): error BC30456: 'Controls' is not a member of 'Skins'. ---> System.Web.HttpCompileException: R:\- Existence\Right Angle\- Public\Sites\rightanglecompanies.com\Versions\New Year 13\Working\DesktopModules\Admin\dnnWerk.Pages\View.ascx.vb(487): error BC30456: 'Controls' is not a member of 'Skins'. at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean ensureIsUpToDate) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at DotNetNuke.UI.Modules.WebFormsModuleControlFactory.CreateModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleControlFactory.LoadModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() --- End of inner exception stack trace ---

I'd like to either get the DNN Werks module to work, or reinstall the original Page Management module that came with DNN 7.  Plus, the same problem with the Page Management module appears to be happening with the Browse Server function in the CKEditor.

Does anybody know how to fix this problem?  Or, does anybody know where to download the original Page Management module that comes with the DNN 7 package?
