Visio XMI 1.0 import error

Hello,

I have Visio 2003 UML activity diagrams. I want to get these diagrams into any ArgoUML. 

I exported UML data out from Visio using Visio XMI export add-on and tried to import into ArgoUML but get below error. I even tried exporting through Visio 2007 but the exported XMI has same content as Visio 2003 XMI.

Will much appreciate any help!

Jay

P.S. 
A Visio sample activity diagram and its Exported XMI 1.0 data file can be downloaded from here for your reference-
