In VNL 2008.10 there is no longer any "Lab Floor" as in old releases. The new method for importing VNL files is either to drop them directly to instruments like the Nanoscope, or use the "Result Browser". If you open this instrument (double-click the icon in the main window), you will find an "Open" button, which in addition to letting you import VNL files also supports import of xyz files.
Once the file is open in the Result Browser, you can inspect the content of the file, and drop (from the left panel) the relevant configurations to other instruments, like again the Nanoscope.
