*egg on face* I expected the log to be on my desktop, like the install log was, but now I found it inside the x-plane folder. So sorry for the confusion on my part.
I have it installed on one of my many partitions, not my C: drive ( I keep C: lean and mean )
When connected to the internet, even if only briefly when just launching it, the x-planewill start up 'normally'.
Attempting to attach log :)
