</div>Hi Erik,<br>
<br>
OK, I saw the list of supported architectures and noticed it contains<br>
IA64 but not AMD64 if I read it correctly.<br>
<br>
I'll investigate and see if I can get more debug for you. In the<br>
meantime I have a 32-bit machine to run on so I can study the examples<br>
as well.<br>

Cheers,<br>
<br>
Ian.<br>
