Cannot export .blend to .smd. Thread

I'm trying to use hl2export-0.3 as available from these forums with blender 2.49a.

Is it necessary to rig an armature for every model? I'm just trying to export a simple physics prop, which doesn't need any bone data.

I thought I read in the tool's thread that the script will automatically create a bone if no armature is selected, but it doesn't seem to be working for me. Could Dragonlord (or someone else in the know) chime in and shed some light on this? My models are needed for a new map and the competition deadline is in just a few weeks : \

Thanks in advance.
