Hi Mouse Gap....... I really don't know anything about Vista as I still have XP.... But I'm wondering why 7 dlls were needed...never heard of so many...... I only had make sure I had 2 Dlls which I listed on another post about plugins.....
Did you try do a search of each dll by the exact name it should show how many you have.... just delete one from there.....
Have you deleted the plugin and then found it from another plugin site.. you might have gotten a corrupt file of it..... I've never had any problems with that set of plugins.. try that and if that doesn't help I could send my files see if they work....... sorry couldn't be more help.......
