GSX errors in FSX after latest update v3.5.3 dated 29 May 25

[garybarker]

Since downloading the latest GSX update version 3.5.3 dated 29 May 2025, I am experiencing the following in my FSX version: (1) Upon saved Flight loading, a red message appears at top of screen saying " [GSX] A simulator update has been applied, please run GSX level 2 Control Panel, and click the Disable Default Jetways button" Upon checking my GSX level 2 Control Panel, the Disable Default Jetways button is already clicked. At this situation (saved flight) GSX still loads okay and works okay, however (2) when I add a different Aircraft to the same flight, the following GSX Error log appears, and GSX does not load or work
 "couatl v3.2 (build 5740)

Hello,

I too had this issue since the May 29 update. One thing I tried was downgrading SODE to 1.7.1. Fingers crossed I have not had the issue since.

Try that and see if it helps.

Thanks Peter. I already use SODE version 1.7.1 so still have the problems after the 29 May update. GSX also crashes with a similar log error when landing at the end of a flight.

Guess I jinxed myself, got the error on landing.

Oh Well
