Crashing after startup
 

I had gotten Omnigraffle 6 installed while running Mountain Lion and it worked fine but now that I'm on Mavericks it crashes within 60 seconds of opening without fail.

Obviously I can't use it like this ... is anyone else experiencing this problem? If there's anyone from Omni on here, please let me know if I can provide any log files, etc. that will help you reproduce/fix this.

Same thing happened to me.

They're working on a fix, and told me to revert to 5.4 and they would give me a refund.
