[ISSUE] RoomWorks activated = No Sound

Hello guys, this just happened to me right now.
When RoomWorks is activated , my track just stop , but a really loud noise instead.
When i turn it off, the music come back to normal, without the reverb, of course.

So, i dont know what’s going on.
Anyone could help me?

I dont know if it’s worth to mention , i’m using Cubase 7 for MAC.
