I think you have forgotten some space before starting the xml starting tag

<?xml version="1.0" encoding="UTF-8"?>

Check the system log for more details .

To do some debug where the error is comming, create a test.php file in the root and add this :

<?php
require_once('./app/Mage.php');
umask(0);
Mage::app();

// enable user error handling
libxml_use_internal_errors(true);

$root = './app';
$iterator  = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($root, RecursiveDirectoryIterator::SKIP_DOTS),
    RecursiveIteratorIterator::SELF_FIRST,
    RecursiveIteratorIterator::CATCH_GET_CHILD
);

foreach ($iterator as $path => $item) {
    if ($item->isFile() && $item->getExtension() == 'xml') {
        $xml = simplexml_load_file($path);
        foreach (libxml_get_errors() as $error) {
            Mage::log($error);
        }
        libxml_clear_errors();
    }

    }

Check the output and fix the errors . See this link for more info link (If that doesnt work for you than see the option of the ip restriction .)
