Okay, it REALLY does not like your openAL32.dll file. If I use it, I get that error.
If I use either MC's or MOUL:a's , it tries to log on to their server, and that won't work (MC's is shut down, and of course I'm not authorized to use MOUL:a's internal client.....doesn't like my dynamic IP addy anyways....).
I'm really interested in finding out why it has such a heart ache with your OpenAL, makes no sense to me.
edit: Oh, and I am using the H'Uru script files.
