This happens sometimes when Avenue is confused about the sound card. Go into the Preferences and on the Audio tab select the correct audio device. That should fix it.

Thanks, that fixed it. However, the effects still only work when I drag them into place, no more clicking?

Haha, I see you added "Fireworks" and "Snow Flakes" and more to the Particles effect, handy;-) But....the effects are broken as well, they work for the first time, but upon selecting an other one...nothing happens, it does not even appear in the Clip/Layer or Composition effects:...

Oops! After updating Resolume Avenue all video's with added audio won't work! Even the demo-footage.

When i click it gets stuck on the yellow loading bar:-(



EDIT: BTW, i'm on a Mac(book pro) (Mac OSX 10.5.7)
