The Plugin Site

I'm having problems installing plugins in PSE4. i put them in the plugins folder (PSE4 is not open) but when I open PSE4 they don't appear. I've tried rebooting computer, etc. but nothing seems to work. They worked fine in my PSE3.

Help please.....
Thanks in advance

Which plugins?

Thanks for getting back to me. I really appreciate it. I'm having problems with Vizros Curl, Horizonaus Stripes are In, Distort, Optikverbs virtualPhotographer. They are all filters I used for creating elements for scrapbooking kits.But now I can't get them to work no matter where I put them. I have a few others as well but haven't tried to install them because none seem to work other than the ones that came with PSE4 other than one set I have called "Simple Filters" by Alexander Blair (I think) I finally got it to work.

Thanks so much. I appreciate any help you can give me.

Please check if these plugins really are in the Plug-Ins sub folder of the Photoshop Elements folder.
