[Tractrix]

I've just purchased sylenth 1 buy i can't seem to loacate it on my macbook pro. I saved it into my macintosh HD. and when i load it on logic i'm not able to load the bank presets.
I've also trying to delete the demo version off my mac but can't find the file for that either.
I tryed lookin through the libary under the hd and user name but i have no luck.
