<Resolved, I hope> VPA plugin rejected VPA host.

Original post> Every time I try to load this .cwp I get an error message, fault reporter and Sonar crashes. The error that immediately pops up says, VPA plugin rejected VPA host. Fault reporter then sonarpdr.exe stopped working.. needs to close. I don't think I have changed or updated any plugins lately. My plugin scanner finds them all.
Could it be that someone is using a plugin that I do not have?
 
Any idea what might be causing this?
 
Follow up> From what I've managed to find it is probably a problem caused by IK Amplitude or T-Racks installing new .dll files in a new place rather than over the old .dll files...
PROBLEM... I have no idea how to find what I need to delete or if I delete Al my IK products and re-install will that even remove the old .dll files.
I am going to be more organized when putting plugins, midi, and audio on my new DAW but I yam where I yam on this machine, at that be lost in the woods.
I need help.

Thanks Rain. I may have it fixed. I updated to 3.14 and the .cwp loaded. Fingers crossed. I am updating everything else then, if it is prudent I am going to delete everything else, in other places, older versions etc. I'm not sure if that is the thing to do or not.
