thank u all!!!!!
u're nice to answer that fast, well...

yes, it worked fine so far, didnt change anything in poser.
im loading a hole new scene, use firefly render as always but then, when rendered, the scene is empty...no objects, no figures...i didntr use a background image...well poser 4 render works fine, i now use that one and im happy with it but...whats wrong with firefly???

Restarting poser never worked...hm :(

on rendering, there is just a completely empty pic...
