J-Link failure

I have an application with an LPC2136 using IAR EWARM 4.3 and an old J-LINK-ARM-KS (before rev numbers were printed on the case) running on an XP platform. It has been working for years.

The product is now moving to the LPC2148 and with that an upgrade to IAR EWARM 7.2 with a newer J-LINK-ARM-KS (hardware V5.4) running on Windows 8.

I am having trouble loading flash for debug from the IAR IDE. I get message saying the RTCK is not there or memory access timeout.

I suspect my JTAG connection is not compatible with the newer J-Links. I have been through the Segger docs - no help. Is there an app note describing how to connect and configure the LPC2136/48 for use with the J-Link?
