I had to reinstall Omnisphere and Trilian after Windows 7 needed reinstalling. Ive udated both to the latest versions and authorised both. I can open soundsources from trillian in Omnisphere and I can open VIP patches. but In Omnisphere their is no Trillian patches in the patch browser or Multi browser.
Spectrasonics Support sorted it. It was my stupid Windows 7 ever since the reinstalation or maybe it was the Windows updates all my software has been starting in none administrator mode even though I login as administrator. Right clicking my DAW start icon and telling it to start in administrator mode allowed Omnisphere to open Trilian patches.
