Same problem here since yesterday.
I have already completely uninstalled and reinstalled GSX, tried running the live update several times but yet no success.
Also I have tried deactivating every addon installed, however also with no success.
I am running P3d v4.5 with several add-ons such as PMDG, FSL and many sceneries installed.
No problems whatsoever until yesterday. Since problem occurred GSX is unusable and I am unable to fix it.
Any help/support on that matter would be appreciated.
Please find attached error file generated by couatl.err.
Thank you in advance.
Regards,
Michael
