It's possible that there is a memory leak in the audio playback code of AGS. Did this happen every time you tested the game, or just happened once?
The crash dump file is not for you to read, but contains debug information for the developer
of AGS to find out what happened. You may zip the file, upload it and send the link to CJ
by PM, but since CJ is quite busy atm, he may not be able to check that in a short while.
