I often get this message and I'm not able to reproduce this..
No panic log also..
Using Prepar3Dv2.5 in Win7 64bit. GSX 1.9.12. Couatl v3.0 (build 3169).
me too. mostly happens after installing scenery
To fix, until you have another scenery to add to the library, delete the couatl folder inside c:\program data\virtuali
