No sound with Waves PRS

Hello,

I bought Waves Superamps PRS and it opens well and I can select presets, but I have no sound, well just the ineffectual sound of my guitar.
I apparently know this problem happens on Cubase, but I couldn’t fix it.
I specify that with another DAW it works well (I use Cubase Pro 10.5.20)
Thank you for your help.

Maybe you overseen a bypass button?
I don’t remember such problems with Waves plug-ins.

no the bypass is disabled
