Edit: Note that if your saves are in the ftblauncher or folder just above please save them first. They should not be, but do not want to be blamed for instructing you to delete them on accident. The pack/save folders should be on your desktop in their own folder if you followed the recommended instructions.
Your launcher is showing the old logo for Magic Farm 2. Try deleting the ftblauncher folder in the %AppData% folder for windows and '~/Library/Application Support' for Mac. Then download a fresh copy of the launcher from the front page. Be sure to backup any saves, though they should not be affected.
