Unable to Open Process Route Tab in DIR (PLM webUI page)

Hello PLM Guru's

I am unable to open the Process Route Tab in the DIR Web UI page.I get an error message for "Name: AcfApplet, Publisher : SAP AG , Location :http://..../com_sap_acf_updown.jar".When I click run it keeps running but not opening the Process route page. This does not happen when I open Process route for BOM/Material Master.

Is there any problem with my browser settings or any SAP config?

Kindly advice.

Thanks & Regards
