I'm arranging some Haydn string quartets and found some Lilypond files of them on Mutopia, but when I go to generate them I get an error saying that the version is too old (2.6.0) and that only versions 2.7.38 and up are supported. I'd hate to have to create the whole thing again, so does anyone know an easy (or at least easier) way around this? I tried simply deleting the version number from the text file, but somehow Lilypond still "knows". I can't seem to find an old enough version of Lilypond to download either that might still support 2.6.0.
One possible solution I thought of was to find more recent files providing string quartet "architecture", and just transfer the Haydn music into that. But if anyone has a better idea, any help would be much appreciated!
