I have encountered a problem as follow, after using the EKCH Configuration Tool first time.
When trying to use GSX, on the RWY or at the gates, i recieve this error message;
GSX [system error while accessing file] D:>>>>
flytampa-copenhagen/scenery/af2_ekch_fsx(jets_random)_nw.bgl: create file failed:file was not found (system 2)
i tried to turn back all setting as before, even reinstalled the Addon manager from FSDT, but no luck

When checking the EKCH scenery folder, the af2-ekch/jets_random file was renamed to _nw.off
(also the af2_EKCH_FSX(no_jets) was off) renaming it to .bgl curred the problem.
Take Care
