There is a known bug with Trigger 1.65 and Logic (AU Validation). We are currently working on a fix. For the time being, you can always download/install version 1.64.
If the AU Validation isn't your issue, can you please explain in further detail what you mean when you say "I installed it as AU, VST, and RTAS and ProTools reads it fine and I can use it, but I can't in Logic 9."?
