Out of curiosity, while my Ignite download was finishing, I decided to give it a go on Steam. Same error. I find this really strange. Also, I got a kinky flash of my AVA folder in the screenshot, if you want the other half of it I can send that too.
(This was my C:\Program Files (x86)\Steam\steamapps\common\AVA folder)
This is really strange! Definitely not just Ignite then.
