Greetings,
First make sure that you have run the updater utility, located in your main PlaneShift directory. It may take a long while to get all the files, but many of them are vidal updates. If the problem persists, try turning off sound using the PlaneShift Setup application, also located in that same directory. This is the most common \"solution\" to the problem. Otherwise, please post the numbers that come up with the error, as they usually have an associated known fix, or a clue in the right direction.
