Hi shedking, are you using Lumion 7.5 Trial and SketchUp 2018 or 2019?
If so, the problem is that Lumion 7.5 Trial
was released before SketchUp 2018 and 2019 existed.
Unfortunately the SketchUp developers changed the .SKP file format in version 2018 and 2019 which made it incompatible with Lumion 7.5 and older versions.
To resolve the problem, simply save the .SKP format as a SketchUp 2017
file in SketchUp 2018
or 2019 and import that version in Lumion.
Alternatively, I'd recommend testing Lumion 9.0.2 Pro Trial
as you can import .SKP files that are saved in SketchUp 2018 format in that version of Lumion.
Here's how to get it:Knowledge Base article: Is there a Trial version of Lumion?
