Ipod and Imatch

I can´t sync my Ipod touch.

Once I iniciated Imatch it din´t sync anymore.

I restored it and now I have an empty Ipod.

Besides, Imatch doesn´t work in my third authorised computer.

You can see the library but songs won´t play (or download).

What would Steve Jobs say..."This is ****!"...pretty concepts and products but don´t work.
