Distance of a polyline in a polygon issue

I'm currently trying to find the distance of mulitple polylines(rivers) in multiple polygons(counties)

Tried this and failed.  *ArcToolbox - Analysis Tools - Extract - Clip.  That process returned a unclipped shapefile.
Tried this and failed.  *HawthsTools Sum Line Lengths in Polygons.  I get the following error: LinesInPolys:K -2147216814 The geometry property of the spatial filter is invalid.

Note.  I have Arcmap v. 9.3
My coordinate system is = NAD_1983 as is my polyline and polygon layer.
I have also run the check geometry tool and everything checks out.

Anyone have an idea of what I could be missing? Or know of any work arounds?
