Invigorator can only recognize an Illustrator file with vector paths. The best, if not only way is to create it in illustrator.
Your logo is so simple, you can import it into Illustrator, then just use the pen tool to draw lines (on a new layer) that match the shape of the logo. Then you delete the layer containing the original logo.
It takes a little practice, but drawing with bezier tools is a necessary skill for AE as well as Illustrator. Actually, you could have done it by now, rather than spend time waiting for a response from us. 🙂
