【Help】Failed to create netlist : Error ORPXLL~1

Hi ,there,
My ORCAD runs well recently , but all of a sudden, today I got some error when trying to creat net list. Could anyone help on this? I really do not want to reinstall Cadence 16.6

Following is Netlist setup(default as usual) and Error Screen shot. In the error picture, after I click OK, Cadence stopped responsing and stucked, so I have to end it in windows task manager.

Thanks very much!
