The plugin works ok for me, but make sure that the transparency in your files 
is correct. It is likely that it was exported wrong (reversed) and the scene 
is actually displayed, but all transparent. E.g. the default Blender plugin 
and Google Sketchup export it incorrectly reversed.

An easy way to check for this is to use osgconv and convert the dae file into 
an osg file - if the data are there but you cannot see them, it is the 
transparency problem.
