It is possible the trial version will not export, as often they don't. The trial of Envisioneer 6 will not export anything.

It, is full working trial I have test the exportfunction and it works very well with the max files on the site, only to bad ther isn't any free converter max - 3ds. The only problem I have is to get correct scale
so I will look at site whit free max-files in the trialperiod so I can convert them.
