EPG edit/view utility -errors

've found the EPG editor (downloaded from this forum) to be a very useful utilty to check my guide.xml files. The majority of the time, it works great and displays the EPG. Occasionally, I find that some guides won't display. I have no clue as to why that is, but it's consistent. There doesn't appear to be anything wrong with the guide.xml file, it still works fine.

I would like to know what specifically causes these errors. I would like to correct whatever the problem is, so that I can continue to use the EPG editor to check guide.xml files. It may be something wrong in the config.xml file for WebGrab+, but I can't fix it unless I know exactly what causes the errors.

I realize this is basically unsupported software, but I was hoping that if I post my files, someone might be able to give me some insight as to why it doesn't work for some config.xml files. In the attached files, the guide.xml won't display in EPGEdit.

EOG editor Gives me this:
