Softimage Xsi: importing layout into XSI 2.0 demo

Is it possible to import a layout into the demo? I've downloaded a few 1024*768 layouts, and I drag them over a viewport. The cursor changes, indicating that the link can be dropped. But nothing happens when I do so. The help file says that i have to go to the main menu bar and choose layout->import, but import is not an option under layout. Has anybody been able to change/import a layout into the demo??

Thanks in advance for your help!
