Will you please post the full console log to pastebin.com? There's a lot missing from the top that contains information that helps us figure out why things aren't happening the way they should.

This *might* apply to you:

Go to Control Panel>Java, and then to the Advanced tab. Expand "Security". Are either of the following two options selected?
"Check publisher certificate for revocation"
"Enable online certificate validation"

If they are, deselect them.
