Sample Model and Sketchup export issues

Hi all, I just downloaded the trial version of Open Buildings Designer Connect Edition and have two questions/issues:

1) I would like to know where I can get a sample model I can start playing with to familiarize myself with the program.

2) Exporting Sketchup models doesn't seem to work as the program either crashes or no file is created.  In the latter case the logfile sometimes says: "NO ELEMENTS FOUND" even though it says that the file has been successfully created. 

Below I have attached 4 screenshots :

- The first one is of the model

- The second image shows the Sketchup export options selected

- The third image shows the logfile clearly stating that the file has been successfully created

- The fourth image shows the folder where the file was supposed to be saved, missing the saved file
