thank you!
I'll give that .dll a try..
did you mean OpenAL32.dll
from
http://ftp://opensource.creative.com/pub/sdk/OpenAL11BetaSDK.zip ?
that .dll in that package has no version information...
It would be nice to say what .dll you took

i renamed that dll to lwjglaudio.dll
and my game works... but i haven't tested it on other machines, so i don't know if it fixed the problem...
