For those of us already using Quest3D 3.5.5 there is a new version of the 3d max exporter. This version only works for Quest3D version 3.5.5!

Get the new version right here!

And For the registry hackers amongst us, quoting Tom Beddell:

I have multiple versions of Quest installed. You have to install the version you want to export to last, so that the registry points to the right version I suppose.
