I think it was quite obvious that it didn't say "It was DragonAPI".
what I'm saying is I had the outdated version and I couldn't find a 1.6.4 version okay?
The ONLY official download is here: https://sites.google.com/site/reikasminecraft/dragonapi. If you downloaded it from anywhere else than the links on that page then there is a good chance that it is infected. If by crashing you mean that the game fails to load, then please post the log and crash reports.
