I was having the same problem a lot of others were having and finally fixed it today.

This was the fix i found
1. Go to your FTB Directory and delete it.
2. Go to %AppData% and find ftblauncher. Delete that folder.
3. Go to the feed the beast website and download the launcher again.

Which is the same as the basic troubleshooting guide. Which is what we normally tell people to do anyway.
