Don't have any suggestions for you with respects to PEP v2/3 short of uninstalling/reinstalling though I'm sure you've tried that. That being said, why not install PEP v1.1.20 and see if you have the same issue as you are having with PEP v2/3. If you are able to get PEP v1 down the transition to PEP v2/3 will be a breeze not that I'm advocating PEP v2/3. I'm not. I use PEP v1 exclusively. Would rather chew off one of my own limbs than use PEP v2/3. To each his own though. Good luck.
