Problem in Microsoft Visio

I have been using Microsoft Visio for about a year to draw flowcharts & block diagrams. MS Visio was actually a good tool, in terms of usage like other Microsoft Product & it is smart enough to convert all the diagrams into many type of image formats.
My current project Prima, is a product thats under-development in Saksoft. It has so many modules and each of us have part in designing work also. As per some standards I created a .vsd file(visio native file format) so that I can share with my teammates.
Im using Microsoft Visio 2003 & most of my team mates use Visio 2000. So, there exists a backward compatability issue. The problem is, the file saved in Visio 2003 is not supported by Visio 2000, and that is normal. So I opened the file & tried to save the same in the lower versions like we do it in the Word...and the worst part is that Visio 2000 was missing, only Visio 2002 was there. And actually the file(the one I designed) had half a dozen rectangles & couple of arrows & Texts. Basically, this a simple workout in the Visio but the fileformat is not supported/missing.
Atleast Visio 2003, supports some other formats such as XML drawing, XML stencils etc., but there is no solution for my problem other than re-doing the drawing.
So I have to use one of my Teammates' PC with Visio 2000, to create that .vsd file!!!
