I have encountered problem with running WRC 107 module of C-II V.5.2.

When I would like to open exiting WRC 107 files, error message “Could not open yield stress database” displayed.
And when I would like to select “Vessel Material Name” on WRC 107 vessel data tap, the C-II system is shut-down.

This problem is occurred after I installed C-II update build 100715.
My colleague encountered same problem after last build update.

Please somebody tell me the solution.
