UNITY!!!

It wont work in unity! Hav exported from blender as an fbx, imported as a new asset into unity, the folder comes up, says everything thing is there when I drag into scene, even shows arrows to move it but there is nothing there not sure what's going on but very frustrating. Maybe model has too many vertices, not sure but have tried and tried again to import into unity but I'm not seeing any model! Sounds like alot of other people are having similar problems. Other than got my model and walk cycle all done, just been blogging it up and then burning onto CD now. Not sure what to do about unity will try again tomorrow.
