All of a sudden, my icf will not open properly in iProntoEdit. It opens, but appears as an empty file. The file is there on my hard disk and there are no obvious signs of corruption. Other icf files open correctly. I'm assuming that there is something corrupted in the XML, but I haven't a clue as to what to do about it. Anybody familiar with this problem? If so, do you have a fix? I'm thinking about uninstalling and reinstalling the editor, but, since it will open other files perfectly well, I don't see a good reason that will help.

I will be greatly indebted to anyone who can help with this. Naturally, I have no external backup copy since it was a work in process.
