It's been a while since I used the program, but a couple things come to mind. First, if the vertical bar that you show above is actually in the file name, that could cause problems. I'm guessing it's just a typo, though. Second, make sure cgpsmapper is on your path. Third, maybe try an older version of cgpsmapper?
Thanks for the reply. The vertical bar is a typo in my note. I checked the path and everything seems correct and I still get the error message.
