Mixdown causes insta-crash

Hello again,

I have Blender 2.45 on Windows XP, updated, with a quad-core processor and plenty of RAM, so I don’t think it’s my machine, but -

Every time I try to mix down an audio track, Blender instantly crashes with the message that it has encountered an error, etc etc etc.

I followed the instructions I found here:



Any clues welcomed.
