I have no Dolphin products, and I suspect that my difficulties have something to do with plugins. I went to the Avid website and re-downloaded Sisbelius 5.25 English. I don't know what this will do for the scripts you helped me with, but in any case it didn't help me at all; the missing file is obviously not part of the Sibelius package. So I tried a System restore to a point two days earlier than when the problem ocurred, and that didn't help me either. However, it did give me a clue, for it told me that System restore couldn't complete successfully, and gave me a path to the problem area. I didn't manage to get it all in memory for I couldn't make the speech repeat it, but it was something like the following: c:\user\mr. Fordham\APPDATA\roaming\sibelius software\sibelius5\plugins\access\\jaws to sibelius49 I'm not sure whether the ING meant that or was a plus sign in translation. I hope that means something to you.
