I'm guessing "too many triangles". How many triangles does it have? Or how big is the file size? There are 2 formats for STL files - one is about 50 bytes per triangle and the other is about 175 bytes per triangle. Anyway I would say 100MB is probably about the limit for a file size for an STL. Any larger than that and you probably have features too small to print.

Here's one trick to reduce the triangles: http://www.shapeways.com/tutorials/polygon_reduction_with_meshlab
