<Unkown> add-on try to restart Coualt

[Avero]

Hello! Yesterday I get a problem with GSX. When I edit UUWW AFCAD in Prepar3D v3, and restart sim, I got an error:
"The addon <unkown> is causing the Coualt Script Engine to restart. Please download and install the latest Stand-Alone Addon Manager..."

Log:
couatl v3.1 (build 3625)
panic log started on Sun Mar 05 22:03:29 2017

problem raised by addon <unknown>
Traceback (most recent call last):
  File "couatl\common\fsm.py", line 73, in executeDoFuncToCompletion
  File "couatl\GSX\assistanceServices\__init__.py", line 826, in do
AttributeError: 'module' object has no attribute 'gsx'
{}
User collision geometries reloaded

I install the manager, but error not going on. Help!
P.S Prepar3D v3.4, license. Latest GSX, too license.

This issue has been already discussed on the forum, and it happened because you must have disabled GSX from its menu, see here:
