I recently got a plugin called unmult. It's a red giant plugin that I placed inside my after effects Plugins folder (Applications/Adobe After Effects CS5.5/ Plugins. Well it didn't install at all. It would not show up no matter what I tried. I've now been trying to install Videocopilot's Sure Target 2.0 plugin. I keep getting the same thing. I have no idea what's happening. I installed the 64 Bit version, but nothing is happening. If I try to doubleclick on the file, guess what happens? A message pops up saying
"After effects error: can't import file "suretarget.plugin": unsupported filetype or extention (0 :: 1)"
HELP! No matter what plugin I try to install, it doesn't work.
