Install Izotope Vinyl In Logic

IZotope RX was developed to work on Mac OS X 10.5 or later. The iZotope RX installer is commonly called izotoperxv401b.dmg, izotoperxv210.dmg, iZotopeRXv201.dmg or izotoperxv202.dmg etc. Our antivirus check shows that this Mac download is clean. The actual developer of this Mac application is iZotope, Inc. Once you have selected your install features, press 'Continue' and start the 'Install'. Near the end of the installation, you will be prompted if you would like to 'check for updates to iZotope software', press yes on this prompt, and your plug-ins will be scanned to see if there are any newer versions for any of your iZotope products. Logic Pro X can host both AU effect plug-ins, as well as AU instrument plug-ins. To add an iZotope effect plug-in to a track in Logic Pro, follow these steps: Click the 'Audio FX' button in the mixer channel strip of your audio or instrument track (this is the same button you would click to add Logic's own compressor or EQ, for instance).

Install Izotope Vinyl Logic Pro X

Ever since I updated my macbook to elcappitan OS X, all my izotope audio units and plugins have not worked in Logic. They all worked on Yosemite and Mountain Lion though i'm not sure if the operating system its e root cuz i'm the only one i'm aware of with this catastrophe. The affected plugins include Ozone 6, Nectar 2, Insight, Iris and Stutter Edit. All other plugins from Apple, Waves, fxPansion and linkedvst work all fine. I've uninstalled and reinstalled all plugins one by one and even repaired the disk emissions but all the plugins work except my isotope ones.
Here's the error message when Nectar 2 goes through AU validation:

I get a similar error message on all the isotope plugins ... I feel i might have deleted either a .plist file or .pref file at some point that caused this error of 'no image found' and a simple line of code in Terminal could fix my woes but i'm not a computer expert and I don't know what to do.
Please help?
