Can't install/use Addon Pack

I have installed vvvv and all the signs are green. vvvv is running perfectly, but somehow I can’t use the Addonpack’s Nodes. I followed the instructions from the download page and also reinstalling everything didn’t change anything.

I’am using Windows Vista Buisness with Service Pack 2 installed.

Does anyone know a solution?

can you elaborate on that? what exactly seems to be the problem?

It’s working now. After installing it to another Folder, it worked. Thanks
