I'm having the same problem... I even renanmed the directory from the "dragon-mod9" (from unzip) to "A".. I select all scripts, and understand about it not necessarily hitting 100% for whatever reason, but I get that error, click ok, and it just sits on "clean statics..." No filesizes have changed.
Only other thing I can think it might be(??) is that I moved the .mul from one directory to another before running DragonSP, if that matters? Otherwise I'm' not sure what to do

Any ideas?
@the fella who had this problem before - What did ya do to fix it? I'd move my static.mul's but I already had mine in the dragon directory. Was that all you did to make it work? (moving the files)
