This has been solved. I didn't delete the .BGL files as instructed by the patch.

I just recently installed KMDW along with the patch.
When slewing around the airport I get a CTD within just a couple seconds.
I have the FSDT ORD v2 airport installed a few weeks ago and am wondering if there is an issue with both airports being installed.

Any help would be great.
Thank you!
