Frankly, I would suggest that the mentally handicaped stay away from firepods, and Nuendo.
I would further suggest that the technically challanged should also stay away from Firepods, and Nuendo.

Now now. Let's play nicely. Firstly, I would suggest flipping through the manual. If you don't have the manual, then I would suggest getting rid of that crack and using the Cubase LE which came with your Firepod. Let's face it, if you can't figure out Cubase LE then Nuendo will do you no good.

There's nothing anyone could say here that wouldn't be simpler in the Quick Start Guide that came with Nuendo.

Have you read the QSG?
