Your post is very unclear. What do you mean with:
- "Fsupdate" - Which update and which sim you are referring to ?
- "ORBX errors out right away" - Which errors, exactly, and where ?
- "de3fault airport works without Coautl errors." - So, which "Couatl errors" you are referring to ?
Whenever you report an error, you should always post the error log, one that is made AFTER you enable Logging in the Troubleshooting section of the GSX Settings, so it will include more detailed information we need to know what's going on.
