I got it to work ..kinda
The 3.8 plugins were duplicating the 4.0 as 4.0 install created it's own folder in the vst folder.Got rid of them and rewrapped the UAD PLUGINS.
Now I have this problem:
I can only have ONE UAD plugin working at a time.
Works on audio,aux and master insert but as soon as I insert a second one I have some white noise coming out of my mix.
The Uad meter registered around 25% so I have plenty of headroom left on the card.
I tried it with different plugins with the same result

recision,plates,fairchild,cambridge..
I also tried to tick on/ off the AMD setting with no differences.
I did not touch the buffer yet.
Any suggestion on the buffer setting?
The cpu and pci meter in PT7 are very low in the 12% range.
