Make sure you have SP1 installed. Without that service pack the compiler is

Wave uses Spirit.Classic. It has not been ported/rewritten yet.

As both XML grammars (Spirit.Classic and Spirit.Qi) are compatible, you can
always decide to leave both of them in the code base, switching back for
older/non-conforming compilers.
