Colin, I am able to connect now A forum-offered Microchip suggestion http://forums.practicallynetworked.com/showthread.php?t=6781 to run a repair file seems to have worked. I'd seen this initially but didn't think I'd corrupted anything by uninstalling something and am always a bit iffy about .exes So I have tried it now, although I can't be 100% sure that it was just that repair file and/or a combination of all the resetting of h/w and s/w tried simultaneously that was the fix But thanks for replying anyway -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
