[pluggo] 11 errors loading this effect

hi, total noob to the pluggo scene, just downloaded the demo but cant seem to get anything to work, i either get no sond or messages saying things like "11 errors loading this effect", i am running it through ableton live 7 on a g4 powerbook mac osx 10.4.10, i tried both the audio units and vsts but have the same problem with both! any suggestions, thanks in advance!!
