Problems importing a collada file from Blender

Hello.

Has anyone here tried putting google earth into Blender and then export it as a collada file
to Sketchup?
I have managed to get everything into Blender and everything looks fine there but then when I want to export the file to Collada to put it in Sketchup I get an error message that says textures not found - textures are unknown. Then the whole model becomes black/white. Does anyone know what I’m doing wrong? Has anyone tried this? Thanks for any kind of advice.
