Native instruments crashed validation?

So I have native instruments komplete 9 plugins and have HAD them installed and working for a while now. But all of a sudden logic keeps trying to scan each load up but won't scan anything. (stays at "0 out of 4") So I looked up everything I could and went to the plugin manager and everything native instrument plugin except guitar rig 5, says crashed validation. I tried selecting all the crashed PLs and hitting reset and rescan and it does the same thing. Also I'm using logic pro X and my OS, apps (including logic) and all my plugins are up to date. i also checked the NI service center and everything is verified and activated. Help!
