i have a number of parts such as screws and threaded rodsthat are driven by design tables. These were all created pre 2009.
I can't edit them anymore, if i try to add a new configeration intothe design table i get this error

"You cannot change the parent configuration of "M5x10mm threadedRod" once it has been created.

Exiting design table without completing update."

"M5x10mm threaded Rod" is the first configeration in the table. Iam not changing anything in that line.
Any ideas?

I'm running 2009 SP3.0
The design table is attached
