Has anyone gotten electrical routing to work?

I've spent weeks trying every combination of places for myC-points, number of C-points per connector, manually definingwires, using from-to lists, but my route subassembly gets huge(>25MB) and it takes forever to edit the route (10-30 secondsper change in spline properties).

Additionally, SolidWorks crashes, says it cannot flatten the route,magically deletes connectors from the routs, moves fully-definedconnectors around, and can't find from/to components in the routesubassembly.

When I do get lucky enough for a route to flatten, wires andpinouts are missing (connectors all by themselves on the drawing).

Has anyone been able to make a moderatley complex harness and getit to flatten without crashing solidoworks and have a flattenedroute that is correct?

BTW, the harness I want to make has 65 wires, 13 connectors and 26wires that attach to screw terminals on PCBs. I am using SW 2009 SP3.0SolidworksRouting
