Uninstall your current Java. Reboot. Install the most recent 64bit Java (1.7.0_55 at this time). Reboot. Delete the ftb installation from your desktop. Delete %appdata%\ftblauncher. Download the launcher again and save it in C:\FTB or something similar. Start it up, and see if that did the trick.
You may have to add the C:\FTB folder to the exceptions in your antivirus program.
