Problem debugging with P&E Micro USB-ML-CFE cable

I have been using Codewarrior 6.4 (IDE version 5.7.0, build 2264) for over 5 years now with little problem for code development on a Coldfire ETX board.  This week it no longer will process breakpoints correctly.  It will stop execution at a breakpoint, but then when I try to single step execution the IDE displays low memory (address 00000000 with decoded assembler).  If I then try to resume nothing happens, and if I try to stop I get the message "PEMicroProtocolPlugin : Stop failed".


So far I have swapped the coldfire CPU board, swapped the P&E USB-ML-CFE Rev D cable, attempted to reinstall all P&E Drivers, run the P&E driver test application (that passes OK) and finally I uninstalled CodeWarrior and the P&E drivers and reinstalled everything again.  I still can't debug.  I believe the licensing is OK because I can compile the largish C++ code without errors.  I reverted to an earlier project, in case something weird happened to the project, but it is behaving the same way.


It seems like this is a P&E problem.  I tried installing the latest driver (V11), but it failed to install on my Dell Precision M65 Windows XP Professional (service pack 3) notebook.  I have the V9 driver (the one I have been using for years now) installed.


Can anyone offer any idea what the problem is and how to fix it?  This is especially frustrating because two weeks ago it was all working just fine with all the same hardware and software!
