Hello, I have the same problem. I also have FSX-SE and the process runs fsx.exe The server and client versions are 2.0.61 and 2.0.78 It reports the same error as the user writes in front of me. As soon as I connect Simulator, it says it is a different type of Simulator than the selected database. They can not run. I only have a 30 day demo, but I think it should work. Thank you in advance for your help.
