Hi Pablo,
<< I want to buy the latest SDK for 3ds. >>
There is the IPAS 4 Toolkit and a 3D Studio File Toolkit. Both are available
from your dealer or directly from Autodesk. Autodesk's main number is
1-415-332-2344. Also, you'll find additional source code examples in the
Software Dev Kit section in the library.
