I'm using the latest PX version, and I get this error when I pick any px scheme that contains Hang Glider. The game doesn't crash offline, so I so don't get the errorlog text. If I tried to play a scheme with a Hang Glider, none of PX weapons load, and I just see regular weapons. I tested it out with Steps on a scheme with all regular px weapons except hangglider, and px weapons loads just fine. It's also playable online. Just look at the image for the px_errors as it shows exactly same thing as what it is shown in that picture above, and I've attached pxlog file which may give more clues to solve this problem.
