crash: while previewing offline process

Nuendo 5.1 Mac
OSX 10.6.6
MacPro 1,1

When to preview an offline process of multiple regions using RX2 denoizer and upon preview button press Nuendo crashed.

Attached is the log. Should I just post these to the forum or is there somebody I should send them to directly? Perhaps this is an Izotope issue, not sure.

Thanks much.
