[pluggo] Pluggo synth in Protools 7.3.1cs5

Hello, 
I tried to work with the pluggo synth
in protools without success
neither on the aux tracks or the instruments racks !
none of the synth from the original pack have sound.
do I miss something or is it a bug ?
if it is, it's a hudge one (eurk !)

thank you very much

best 
Eryck
