Openfire Admin XML Error

I am using Openfire and Spark. 2 days ago the Spark log in started saying could not find server. When attempting to log in to the Openfire admin, I am getting the message "C:Program Files\Openfire\conf\openfire.xml XML document structures must start and end with the same entity. I have reinstalled Openfire, hoping this would resolve the issue, but did not. Any suggestions?

When you reinstalled, did you do a clean reinstall? have you deleted old Openfire folder in Program files? Also, you can look at this openfire.xml and maybe paste its content here. And you can also check /logs/error.log
