Hi Sergio,

I do not think so. The error message said "nchnls (2)". Are you using 
any frontend? Are you sure there is no "nchnls = 2"?

Hope this helps,

Just to be sure, try running Csound with teh -v flag.that shoudl show
exactly what it is reading and how it is interpreting it.

Also, wild thought but are the line endings the correct ones for your
operating system?  Sometimes MAC endings can give problkems on Windows
