This error can safely be ignored; what is there in the rest of your error_log?
Nothing, that is the only error, but the game crashes while starting anyway.
I'm getting a similar error, but mine says:
[14:48:30] Error: Server profile not found in servers.lst for server: Lands\el.exe". Failover to server: main.
[14:48:30] Using the server profile: main
Help?
