Problem with Makerbot Replicator 2 and Sketchup exporting .stl

Hi as the topic says i have problem exporting model from sketchup to .stl and i'm using the official plugin..
Look at my pictures to see my problem..

Attachment 3583 1 st picture is how it looks in Sketchup
Attachment 3584 2 nd picture is how it looks when loaded into makerbot desktop

Attachment 3585 3 rd picture shows it in the print preview and this is the result when printed

What is causing this error ? It seems to occur at random places and even in very uncomplicated designs !!

// Cheers

Looks like the slicer is having problems with some of the geometry. Run the STL file through the netfabb cloud repair service before you load it into makerbot desktop.
