Can't import dwg-files

Hello
Of some reason i can’t import dwg-files to sketchup even if i can do it on my dads computer that have the same version. When i go in to import I can’t chose dwg-files of some reason,

Does anyone know how to solve this problem?

the free SketchUp Make version doesn’t support the DXF/DWG format… after running the first 30 days as a trial version of the commercial SU Pro version.
