Flotilla not connecting

Okay, you'll need to navigate into the Flotilla-Offline directory, I'm going to guess it's in your home dir so you can probably do:

cd ~/flotilla-offline
git pull
sudo cp flotilla-wheezy /usr/bin/flotilla
sudo chmod +x /usr/bin/flotilla
flotilla

I'll make the installer Wheezy-aware so this doesn't happen in future.
