not able to create new Site, getting error.

Hi, Getting some server/ runtime error.

Steps that caused this issue:-

• Created a new Site

• Tried to Delete the same site after a while

• It took more than a while (kept loading), then I refreshed the page to see if this will help, I got server/runtime error

• Was not able to login into kentico portal at all

• Later figured out that the folder "Admin" and "App_data" was automatically deleted so had to copy the folders manually.

• Now, the application is running but there is no Sites under Sites application even though the site is running.

• The options to create new site or the import site is still there but the names of the site that display right beneath is showing an error "The UniGrid definition file 'E:\ASPENMemberPro\CMS\App_Data\CMSModules\CMS\UI\Grids\cms_site\default.xml' was not found. Specify the path in the 'Grid path' property of the UI element on the Properties tab. You can enter only the name of the XML file and select an 'Object type' to load the XML definition file from ~/App_Data/{modulename}/UI/Grids/{objecttype}/fileName.xml. If you leave the grid path empty, the 'default.xml' name is used."

How it happened? Even though the place where it displays the site name only is showing the error, how the application is running?

Thanks,
