Just wanted to chime in and say thanks for the uploads and all the help people have put in so far.
Not sure if others have had issues like mine, but I've had trouble with butterfly working sometimes, and then crashing and not working other times. When butterfly crashes, running it in command prompt shows the following error: "ERROR spark.Spark - ignite failed". I assume this is due to force-closing the butterfly server window -- (is there a way to close it "cleanly?")
After a quick google search, the easiest solution was to simply reboot the computer and it should work just fine the next time you run butterfly or ddr.exe.
