Right before it finished downloading, a message saying
"Buildism Error

net.buildism.x:java.io.IOException: Resource not found: resource://objects/Unknown.png"

Go to Start>Control Panel>Java, click Settings under Temporary Internet Files and then Delete Files.

Sometimes I cause that error accidentally during updates, and you might have to clear your temporary files for it to be fixed for you.
