problems migrating magic draw 9.5 to argoUML 0.24

Hi guys, I'm having some problems while trying to migrate an XMI file, that
was made using the magic draw 9.5, to the latest stable version of the
ArgoUML, the 0.24. I followed the tips posted here:
http://galaxy.andromda.org/forum/viewtopic.php?t=2245&highlight=migrating
I've already made the copy of the files from the andromda dir to the argouml
dir but still, when I try to open the model in ArgoUML I keep getting this
exception: XMI format error : org.argouml.model.XmiException:
javax.jmi.xmi.MalformedXMIException:
org.netbeans.lib.jmi.util.DebugException: Content is not allowed in prolog.

The model is extremely simple, it has only 1 class with a single attribute,
and of course it uses the andromda uml profile.
(I'm trying something simple, so i can migrate the more complex models
later)

The XMI file can be found here: http://ccsa.ufrn.br/raphaelm/Test.xmi
or here http://www.engcomp.ufrn.br/~rocknroll/Test.xmi<http://www.engcomp.ufrn.br/%7Erocknroll/Test.xmi>

I'd like to thank you guys in advance and congratulate for the great project
that ArgoUML has become.
