OK, I have one instance of this file on my machine and it's contained within a folder relating to the CSound synthesizer - do you have CSound installed on your computer? Additionally, please do the following: 1 - Bring up the Run dialog by holding down your Windows (Start menu) key and pressing R 2 - type in the following, then press the Enter key: Cmd 3 - You should get an old-fashioned command line, so type in the following, followed by the Enter key: Cd\ 4 - Type in the following, followed by the Enter key: Dir lua51.dll /w/s/b This command should find all instances of the lua51.dll file on your machine and may take several minutes to complete (The command prompt should reappear on completion). Please note down where any instances of the file are located and post back to this list. Best wishes.

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.
