Windows .jar LWJGL problem?

[vince959]

Trying to place the wireless transmitter in Unleashed v1.1.1 and I got disconnected from the server with this error in the console

2013-08-02 03:38:04 [INFO] [STDOUT] Error in class 'SourceLWJGL OpenAL'
2013-08-02 03:38:04 [INFO] [STDOUT] Channel null in method 'stop'

Tried to update LWJGL to latest 2.9 and still the same, but I think some other players can place the transmitter down without problem. But I have no idea why my client is doing this.
