I recently downloaded Addictive Drums XLN Audio.
Tested it with in a new project and everything seemed to work fine.
After a couple of days went back to use Addivtive drums on a new project and could not find it anywhere.  Not in Instruments, not in Synths
it was nowhere to be found. As if it never existed.
As anyone encountered this situation?
What is the problem? Did I do anything wrong?
Thank you in advance for any help.

Try rescanning your vst's.

Did you change your Plug-In menu selection somehow? Mine defaults to X3 Producer effects which doesn't list everything because you have to customize it. You should change it to All Plug-ins and see if AD comes back.
