I installed the stand alone manager and now when I start P3D, I get the following error message.
Couatl Scprting Engine for FSX/ESP has stopped working.
Problem signature:
Problem Event Name: APPCRASH
Application Name: couatl.exe
Application Version: 3.1.0.3527
Your version is newer that the one you had before, but is still outdated.
You must have installed the Stand-Alone Addon Manager earlier today, since we just had another update today, so you still got the outdated version.
That doesn't mean the old version you have was "supposed" to crash, because it generally didn't, but we found and fixed another possible chance of crashes (on exiting the sim), so it's possible that, even if we cannot replicate a crash on startup, it might be possible the current version fixes a crash on startup that, is happening on your system only.
So, install the Stand-Alone Addon Manager now, in order to get the current version.
