Apologies for the delayed reply.
I managed to track down the uploader of the files and contacted him regarding this issue. He replied by stating the default/included server_config.xml contained several errors. He has now reuploaded the files with a working server_config.xml: https://rzumer.tebako.net/lag.zip
The server now starts on my desktop, but ideally I would like to run it on my server, where it refuses to start. I did some experimenting and also spun op a Virtual Machine, but it looks like it requires a dedicated graphics card in order to start. I.e. onboard graphics are not sufficient and the server will be stuck on this screen:

At least I got one step closer, but now I have to troubleshoot this issue. Let’s see if ProcMon can give me some insight of what’s happening behind the scenes.
