There is just an "error:null" immediately after loading the configuration file if I try to compile. If I remove the Genome2d SWC from my library, things go back to "normal" - the endless list of errors I get, including ones from Genome2d missing.
I am going to try updating FlashDevelop but I don't think that's the issue. I'm fairly up to date.
Edit: This is against the most current dev mark.
