The Plugin Site

Hi Everyone,
Can someone please tell me why I can't get Funhouse plugins to work in Paint Shop Pro version 9. They are showing up in the EFFECTS but when I click on anyone of them I am getting this message:
Paint Shop Pro was unable to load requested plugin filter. The plug-in may not be installed properly or maybe missing files.
I have tried various methods to rectify this but to no avail, even downloading them again. Can anyone through some light on this problem please.
Thanking you kindly,
Patrizia

Hi,
I have finally got them to work. I put the plugin.dll into the Windows folder and presto.
Cheers,
Patrizia
