There is a little program that the guys at Filter Meister made to fix all filters made with the Filter Plugin Creator. I fixed all my Toadies, Xero's, & some of my Mura's that weren't working. It's pretty easy to run.
A couple notes though:
first make sure the plug-in you want to fix is in the folder that PSP is pointed to (mine is C:/Plugins).
Once it's in there start the FM Patcher you want to choose the Patch folder option (for some reason the file command wouldn't work for me)
Find you way to the folder that the plugin is in (if they are in thier own folders you will have to do each one)
Click patch it should show you in the box that patch was successful and backed up.
Then the filter will work no problem.
