Indigo Exporter not working.

Now that the Indigo website was back up :D, I decided to try out Indigo 0.8 (before I used 0.6). I downloaded the beta exporter, Blendigo v0.8t2 beta 1d. When I run it, I get this in the console:

Compiled with Python version 2.5.
Checking for installed Python… got it!

BLENDIGO v0.8t2 beta 1d

Windows-platform: win32 os.sep:
Traceback (most recent call last):

ine 90, in join

TypeError: object of type ‘NoneType’ has no len()

Does anyone know what’s wrong?
Maybe it is because I’m using Blender 2.44 with Python 2.5? The exporter is for 2.43.
