OK,
Because of the DIRTY website-change of BOL. I made a quick and dirty update of the plugin.
Version 1.8.0. See the start-page of this topic.
Bol seems to serve different xml-pages for the same object in a random way.
That makes it more complex for the plugin to analyze and find the (right) info.
I think the plugin will do again where it is intend for: finding metadata at bol.com
Please let me know if you experience problems
Otherwise: ENJOY
Thanks Dompie for reporting the website change
