Suddenly Stopped Working

Jul 22, 2013 at 1:00 PM
This webpart was working fantastically right up until this weekend, when our network guy ran the Microsoft patches on all the servers. Now, it simply shows this error:

Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.

Correlation ID:fa3d3e3e-8a9d-4db7-aaf1-dd07945de0e9

And I can find nothing about this online. Any help would be great. We REALLY liked this webpart!
