[Plugin: Warcraft News] Not Updating & Warning Error

Had the widget up for about a month and then suddenly about a week or so ago it stopped updating. So I uninstalled and reinstalled and now get error:

“Warning: filemtime() [function.filemtime]: stat failed for /home/content/72/6434772/html/dissonance/wp-content/plugins/warcraft-news/cache/guild-us-kel%27thuzad-dissonance-en in /home/content/72/6434772/html/dissonance/wp-content/plugins/warcraft-news/warcraft-news.php on line 77
Armory not reachable or guild not found. Tried to fetch this Link. Armory might be blocking, please wait and try to increase cache time.”

It’s been saying this for about a week now. Please help
