You need to verify that the files in the directory install/data still exist.

Specifically the error you're getting suggests that admin_navigation.xml is either missing or corrupt. If it is there, you may want to download the XenForo package and re-upload all of the files.

If you refresh the page a few times, it should get past the error.
