In the 24jQTEffects tutorial part b, clicking on the qfx_read luv.qfx message generates the following error in the max window:

error -1 opening .qfx file for read.

I get the same error in the jit.qt.effect help patch.

I'm using a demo version of max 6.0, downloaded a couple of weeks ago on a PC running windows vista.

I also can't seem to get the addfxtrack part of the patch working either, even when I load luv.qfx directly from the media directory, or when I try and use my own effect saved using qfx_write.
