that's interesting. I just had this problem with a custom(crashing to desktop). Isolating the files I found out the lead arrangement .XML was the problem, then I went back to EOF and did everything I could, I even got to the point of deleting all of the notes and sections and it would still crash. as a last resort I copied the notes and imported another .gpro, then deleted the new notes and pasted the old ones. That solved the problem. I read in another topic that EOF don't copy tech notes when you copy the normal notes, so that was probably it.
