The above errors occurred because the script could not properly determine the existing state of those db elements. Your store may not need those changes. Please post any errors on the forums to ensure that they can be addressed in future versions!

I just feel, that someone tried, to use a complicated DB-Prefix, for unknown reasons, and now, something does not work, because of this.
vangbfzr_gammel.product_option_description

But, because of that, it does not need such a 'symbol' of 'attention', I assume...
