Which version of the CellML API are you using? I am personally using the
latest snapshot (15 July 2013) and it works fine for me. However, looking at
your code, I can see that you use the 'old' way of doing things. I don't
know whether that 'old' style is still supported, but what is certain is
that, ideally, you wouldn't use already_AddRefd, RETURN_INTO_WSTRING, etc.
anymore. See here
<https://github.com/opencor/opencor/blob/master/src/plugins/support/CellMLSu
pport/src/cellmlfile.cpp#L163> for how things should now be done.
HTH, Alan.
