Solidworks 2010 Routing

I have a routing assembly with two ring connectors and one wire.  I used a from-to list to create the harness.  It behaved well for quite some time.  Now it keeps asking me to re-import the from-to list.  The from-to list is stored in a folder on my network.  Whenever I re-import the from-to I use the stored from-to list, Solidworks says it is working correctly, but when I exit the sketch, the error returns.  A new from-to list is generated in the folder where the harness assembly is stored (different from the network folder).  How do I make this error stop occuring?
