Adobe has come out with Creative Cloud 2014. Of course, they didn't warn anyone that Creative Cloud 2013 (for want of better label0 plugins might not, or more likely, will not work with their latest and greatest.
People who had CS6E/CS6 had the same problem. I worked at it until I solved some of the "plug-ins for CS6 will not be updated to work in CC." I had this problem with CS5 to CS6, and by spotting that the plugins worked in the 32bit Photoshop CS6, I manually copied the plugin files, their associated DLLs and activation tool, they all functioned perfectly in CS6E 64bit.
Along came CC, and the the trial, I had the same problem. I found out manually copying the plugins to the 32bit Photoshop CC 2013 worked just fine, but but not in the 64bit, so I had to be careful of the work.
Every thing I have works just fine, the only thing I can think of having to do, it keep a 'past it's trial date' version of CC on the hard drive so I can download and install latest Camera Raw, if necessary. I have that work around so I can use CS6 Adobe Camera Raw in CS5 Bridge. That's too handy of a trick to lose.
