Sounds good. Please let me know if trying from another location helped.
In the mean time, could you please send me a copy of your App Home log to see if I can get more information about what may be causing this?
You can find it by launching Finder and press command+shift+g and paste “~/Library/Application Support/Airspace/” in the text box. Please send the log.txt file to me at firstname.lastname@example.org
