Plugins

Hello. It seems plugins is not possible any more? I have the Redfield plugins since years and love them. No I have a new computer and downloaded the newest photoshop but get an error-message every time I start up Photoshop: "One or more plugins do not exist". And when I try to start the plugin it says "could not do your command cause of a writing error" (in swedish...)

It has always worked for me

I tryed to re-install photoshop but get the same error

Someone had same problem? How to solve it?
