This.
OP, start with Michel Thomas, it will really kick start your language learning (or solidify your foundations). I was amazed how much I learned with his 8-hour beginner German course. I'm about to go on to the advanced one now.
Pimsleur is also useful, but not as intense or fast-paced. It uses native speakers and will really drive things home through the constant repitition. It can be hard not to fall asleep though because the tapes really are boring.
