Can't reopen old file in ver 0.9 or 0.9.1 on Red Hat 9 ( Shrike )

<story>
I had a workstation (a few hours ago) with Red Hat 7.3 on it.  The new 
boss wants a project time line for something I'm working on, so I pulled 
up mrproject.  Put an hour or two into learning the the software and 
creating my first project plan.  Very cool tool.  I like it alot.

It wasn't very stable, so I went searching for a new version.  I couldn't 
use the new rpm's for RH8 on my old RH7.2 box, so I used this as an excuse 
to upgrade to RedHat 9 or Shrike.

So, using the default rpm that comes with Shrike (0.9.0), now I can't read 
my old project file.  I get an error message like: 

Couldn't find a suitable file module for loading 'FILENAME'

So, I upgraded to 0.9.1 and still get the same message.  Here's my rpm 
info:

$ rpm -qa | grep mrproject
mrproject-0.9.1-cf1
libmrproject-0.9.1-cf1
$ 

I found some messages from mid-April 2003 where some Alan Pence's message 
was talking about something similar.  I checked my directory permissions 
and they look fine.

I figured that since mrproject used XML based files, that I should have no 
problems, but alas, I've hit a snag.

Here's what the top of my data file looks like, if this helps:

<?xml version="1.0"?>
<project xmlns="http://mrproject.codefactory.se/format/project/1" 
name="UNIX Environement Hardening Phase 1" company="Hidden" manager="Mark 
Jeanmougin">
  <tasks>

Any hints?  I'm looking at a saved project from 0.9.1 and it is a 
different format, but it doesn't look that far off.  Is there a converter 
utility or should I write my own?

Thanks in advance for any help,

MJ
