Couatl Engine failure

[Probie]

Just bought KLAX V2 the other day and have tried everything, but still cant get the buildings to stay. When I start FSX the buildings usually appear but after approx. 30 seconds or so they disappear. Sometimes I get the message that the couatl engine has failed, sometimes no message. When the building are visible I have both the drop down menus: Addon manager, Couatl, and Vistamare. Once the buildings disappear I just have the addon manager. I have downloaded the stand alone addon manager and turned off my antivirus for the install, as well as excluded the files from scans.

Here is what im getting in my error file:

Couatl v2.0 (build 2193)

Thanks again.

You are not using the current version of the Couatl program, just reinstall KLAX (don't need to download it again) and you'll get the updated version.
