When you have the version mismatch error that is caused by the DRM.
Please check the following things:
1) Did you install XStoryPlayer on the same machine as you downloaded it on?
2) Make sure you keep your internet adapter enabled. XStoryPlayer does not use it, but it needs to check if the ethernet card is still present.
3) Make sure you enable XStoryPlayer in Avast! This virus scanner has (too) strict rules regarding software that is downloaded.
