help (halion and prologue arent giving me sounds) please help

heya gang…
recently purchased Cubase elements 10, I have got drums and piano on Cubase elements 10… However I cannot seem to get prologue and halion sonic working for myself… Is it possible if someone helps me? someone anyone x

Sure but you will have to provide more information. Have you created an instrument track with prologue or halion sonic se and selected a preset? What have you done differently than drums and piano. Are the drums from Groove Agent SE? Where is the piano from?
