batch export in Blender 2.5

Hi,

I’m trying to export from Blender 2.5 using python scrip in command line.

If I execute something like this:
C:\Program Files (x86)\Blender-2.5-alpha2-win32>blender.exe -b “C:\Users\Paulius\Documents\Downloads\Camero\Assets\Camero.blend” -P “C:\Program Files (x86)\Unity\Editor\Data\Tools\Unity-BlenderToFBX.py”

I get an error:
Error: Unable to open
Traceback (most recent call last):
File “<string>”, line 1, in <module>
File “<string>”, line 7
print ‘error: export_fbx.py not found.’

It looks like Blender is unable to locate python modules. Is there something I need to do to get it working? Set some paths maybe? Is the problem caused by the lack of installer?

Thanks,

BUMP !

As this problem is very annoying, preventing us using Blender 2.5x with Unity, staying in 2.49b !
