Thank you for replying Umberto. I changed the hotkey to "F1" for Couatl but it didnt help.
You can't assign a key already used by FSX. F1 is the default key for "Slew down fast". Use a free combination. The best one, is of course the default one, CTRL+F12.
I dont have the IVAP program as far as I now. (I dont know what the IVAP program is to be honest.)
Then you can use default key.
This really is a great product and I want to use it all. I have KLAS and KLAX and want all the US airports, but I want this to work first.
GSX surely works, but there's a problem with your system, maybe you have a permissions problems or a Windows registry problem. Try the following:
open the Notepad and type the following on a new blank file:
logFile=couatl.log
(please note logFile is written beginning with a lower case L and a capital F )
Save the file as couatl.ini in the FSX\fsdreamteam\couatl folder, so it stays at the same level of the couatl.exe. Then go in FSX, then when it's done, press the CTRL+F12 key ( you have of course redefined it before ), then exit, and post the content of the Couatl.LOG file that should have been created inside FSX\fsdreamteam\couatl folder.
