gmax doesn't allow scripts to export to file. Bluestreak streams to gmax's listener window instead. GrabListener is a program written to grab the text from the listener window and ask where to save it. You can download it here: http://hce.halomaps.org/index.cfm?fid=2823

Too many actors means more than one root frame. Press H, and check Display Subtree. If you're exporting a bsp, it should look something like:
frame
. editable mesh

not like:
frame
editable mesh

so you probably need to link the mesh to the frame, making the frame the mesh's 'parent'
