Problems Launching Black Plague Demo

[Luis]

First of all, uninstall OpenAL in the control panel. Then make sure no OpenAL32.dll or wrap_oal.dll is in your Windows/System32 folder. If you find any, delete them. Also, there can't be any of these files in your game redist folder.
Then, install the updated OpenAL redistributable, and make sure you can find the proper files in Windows/System32. That is,
- OpenAL32.dll, version 6.14.357.22
- wrap_oal.dll, version 2.1.8.1
If you wanna make extra sure these are being used, copy them to the game redist folder, overwriting the previous ones in case they are there.

Don't use older files, as they won't include alSource3i for sure. There are some versions that do, but I'm not sure which ones they are, so best to use the latest.
