Worked! Thanks to this awesome guy!
This may be related to some issue with Internet Explorer (the launcher uses the IE framework). I would first reset IE back to it's default state (and make sure IE isn't disabled):
I'm assuming you're running Windows 7 with IE9.
To reset Internet Explorer settings
Close all Internet Explorer and Windows Explorer windows that are currently open.
Open Internet Explorer by clicking the Start button Picture of the Start button. In the search box, type Internet Explorer, and then, in the list of results, click Internet Explorer.
Click the Tools button Picture of the Tools button, and then click Internet options.
Click the Advanced tab, and then click Reset.
Select the Delete personal settings check box if you would also like to remove browsing history, search providers, Accelerators, home pages, Tracking Protection, and ActiveX Filtering data.
In the Reset Internet Explorer Settings dialog box, click Reset.
When Internet Explorer finishes applying default settings, click Close, and then click OK.
Close Internet Explorer.
Hopefully, this can resolve the issue.
