solidworks is crashing when i install fittings

I have a route drawn and i'm wanting to go in and installfittings at points on my 3d sketch. I drag my fitting in, rotate itthe way i want it, and drop it. Every time the program crashes. Iam running service pack 0. Could an install of the 3.0 service be afix for this or do I have another problem?SolidworksRouting
