Weird Nexus problem

Having this really weird problem with Nexus inside Reaper. I start a new session and load nexus on a new track, select a sound, lay down a midi track, and freeze the track Everything is fine... I create another track with nexus on it, the default nexus sound is working fine, but from the moment I select another preset sound, the volume knob of nexus jumps to 0, when tuning it back up again, there's is no sound, whatever preset I try to select, it's always the same scenario, volume knob to zero and no sound. Seems like I can use Nexus within reaper, but only once, on 1 track, 1 time. Same thing happens if I unfreeze the first track and try to select another sound on that instance of Nexus. Re-opening session, re-launching reaper, restarting computer, nothing helps! Only thing that does help = starting a new session, from that point I can use Nexus again, but only once again! Nexus is working fine in Nuendo on the same computer.... Any ideas ?

I have the same problem : The default sound in Nexus plays fine, but once I select an other sound, everything stays quiet. It seems that all controls on Nexus are set to 0. Peter. PS : Nexus is working fine in Cubase 6.

I have encountered the same issue and have opened a ticket with reFX. Hopefully there will be a solution.
