Aria engine greyed out

[UltimateVibe]

I am using GP04 with Sonar X1b. There seems to be something not stable about this engine with my host, unless there is something I have installed incorrectly. When I load a session into my DAW and click on the Aria engine, the image is greyed out. If I move the engine around sometimes the image comes back but I cannot manipulate any controls. The bizarre thing is, this only happens sometimes. Right now it is happening and I have reisntalled the engine, downloaded updates and nothing is changing things. Someone please help!

Windows 7, gobs of ram etc

Nothing like an intermittent bug to make me pull the few hair I have left
If I understand correctly, the interface doesn't show up. Is it just a grey window the size of ARIA Player? Does the sound still play?

On a side note, Cakewalk just launched X1c, you may want to try it, see if it helps ...
