Sketchup expoert

I use Sketch up 2014. I now use the free version. I am also in Second life and Inworldz. When I bring up my model in Inworldz in works great. but with Second life it say’s there is no mesh. I have put in a ticket to sSecond life to see if they know why. I have others I have put into there so I was wondering if you have any idea why this might be happening. I am going to try a diffefrent viewer to see if that solves my problem. But if you have any idea please let me know
