Importing .obj files into Simple Demo

I have several objects I have created and exported out of Blender in .obj
format ... As I attempt to import them using Simple Demo I get an error
message.  Am I missing a step (or should the size ratio be adjusted?)

Thanks for your assistance !

What error message did you get? Dont forget a color in your obj-File.
Without at least one color spezified, you get an error.

Enno

I tried a simple sketchup .obj exported file and get the same error as well.
Here is the error log:

Thanks for you help !

=============

 ??

There is a newer version of the OBJ importer on the Jabberwocky
repository that has a lot of fixes.  If you can figure out the
instructions and get by the warnings at
http://croquetconsortium.org/index.php/Keeping_Image_Current then you
can use this newer version.  I notice that they didn't replace the
menu item with it though - you'll have to call it or update the menu
item on your own.

If you have questions or problems, you can email this list or me.

I had hoped that there would be a newer image with these updates
available by now, but it hasn't happened.  I think that the main
developers don't feel that enough progress has been made on the goals
for the next release to warrant the effort it takes to put one out.
Maybe an updated image should be a separate thing from a full release.
