Now it's my turn to apologize for not responding promptly
Thanks so much for working with me - if you need access to a server, I'm more than willing to set one up on yet another Hetzner and supply you with a login... perhaps you can see what is going on.
That said though, the server seems pretty much perfect. Everything works now, thanks to you guys. It's just the client that is acting up in two different ways.
UruLauncher (Gehn version) installs all right and downloads the data files. But then when the game is about to boot, it will hang at "logging in" and the server will display a message "[Auth] Wrong Build ID from 123.45.67.89/61109: 26"
Nothing else will happen after that.
If I try the same with the Destiny client (plClient.exe) AFTER UruLauncher has finished the initial download, the game works perfectly on my main Windows 10 machine.
However, on every other machine I have tried (all Windows 10), plClient will start, but then there is no sound at all. Also it won't load the game all the way, it crashes right at "Loading age... Personal. StartupHelpGUI". I do believe both those problems might be related to OpenAl, but even when I manually install it (or try various versions found on the Internet), the same will happen on those two computers no matter what.
No idea what is might be, hoping that you guys do
Update: I just tried it on a 4th computer, and that one crashes as well. That means that the one working computer is a fluke and crashing is the norm, since it's happening on all three others
