Meanwhile I have hosted my own LFS-Server, runs only in the evening.
On this Server named HoR Training runs Kyoto International Reversed, and I have Ario working.
The thing is, that I have copied the K31Y.lyt to the layout folder of both (LFS-Server and Ario). I mean that TFalke55 has loaded the .lyt only on the LFS-Server, and than Ario cannot work properly.
By the way, there is still a password on the OEC Server.
