The Collada file exported from SkUp should have the .dae geometry file and a subfolder for textures. Haven't yet tested the new M2 with SkUp Pro yet, but other users report all is OK.
When you add a new model in Lumion you need to make sure the file dialogue is displayng the file types required. So select from the file type drop down and you should see the .dae file for the Collada geometry in the root folder of the export.
Note the (older) tutorial video 3 for Importing shows a dialogue that has *.* All files, this is not in the current version. The dialogue file filter defaults to Object Files .dae, .fbx, so you should be seeing the Collada file in the root folder above the texture export folder.
Perhaps there's an issue as you mentioned with the "use selection" when exporting, must have a play with the new M2.
edit:
installed M2, selection seems OK, but only tried one quick test
