Hi Erik,
I've created modified versions of the EDCommon and EDMessage frameworks with the deprecated methods replaced with current methods. Is this something you have already done in your version of the code or would you like a copy of my changes and if so do you want the full source or just a patch file?
Essentially it was replacing occurrences of 'stringWithContentsOfFile:' with 'stringWithContentsOfFile:encoding:error:' and replacing 'stringWithCString:' with 'stringWithCString:encoding:'. I also replaced an occurrence of 'stringWithCString:length:' with 'stringWithCharacters:length:'.
