Unknown addon causing Couatl to restart **SOLVED**

[A51Rene]

Dear FSDT,

I am having this issue with the Addon Manager at KJFK:

Error log:

couatl v2.0 (build 2376)
panic log started on Fri Jan 02 22:37:32 2015

problem raised by addon <unknown>Traceback (most recent call last):

What I have tried:
- Restarting FSX
- Rebooting
- Installing Standalone Addon Manager
- Installing full GSX installer
- Reinstalled KJFK
- Deleted /appdata/roaming/Virtuali
- Check writing permissions for user files, all folder have full-control

GSX works fine on other airports, but as soon as KJFK is in the vicinity, this error pops up. I haven not yet checked my other FSDT airports.
What can cause this? I have no other problems whatsoever, my FSX is completely stable for once...

EDIT: Geneva works fine, no errors at all. This looks like a KJFK-specefic issue, sorry for posting it here.

Thanks in advance!

Fixed the problem:
- Deleted Couatl folder in FSX/fsdreamteam
- Deleted KJFK
- Reinstalled KJFK & GSX

That's strange, because just reinstalling should have the same effect, however it's good you fixed it.
